@sladow-noob Haters gonna hate! Juust kidding, I appreciate the honest feedback. It started like that, most important ones. But then I just felt everything is important. Many times I've been chasing down T1 artillery only to realize they were Seraphim and can retreat over water. Now I know exactly what to expect. But hey, I salute anyone who can keep track of all those details with the traditional icons. The idle overlay will probably get two versions in the end, blinking and some simple flag much like the idle enginers mod, and ofc an option to chose either or none. The blinking is rather slow and syncronized so not super annoying, but a work in progress still. 
Color coded strategic icons
Congratulations on the V1 release @FreadyFish! I downloaded the mod on the vault and gave it a go. Normally I really struggle with identifying stuff with the default icons, and your mod helped me a bunch in that regard. Many thanks 
My favourite features were the colour scheme matching the capabilities of the units and icon size representing tech level. These were awesome for determining how best to smash an enemy's army composition.
At first I found the navy icon ugly and weird. Now I can't live without them. They are just so FUNCTIONAL. I can tell at a glance if I need subs, gunships or frigates to counter a naval composition. It was especially nice seeing if something had torpedo's or not. I didn't know the Galaxy had them until I installed your mod!!! Wish I'd known sooner...
Some icons weren't to my taste, so I've just deleted the image file for the corresponding unit (it was the spider). Ez fix 
It is really commendable that there aren't tons of obviously asymmetric icons. Many other icons on the vault have asymmetric icons which I find really distracting.
I found a few issues that I hope get addressed in the next release. It took about 10 open-then-close the game to get the shield icons to stop glowing except when zoomed out to the extreme. I also haven't been able to hot-fix the idle factories functionality. Without UI Mod Tools, the fac's show as white (and all idle monitoring also doesn't work obviously since UI Mod Tools is a required mod), while with UI Mod Tools they show as grey except when on repeat build.
Please keep soldiering on! Your mod is great and I'd love to see it in its finalised state 
Something I've been wondering about is icon size scaling based upon camera zoom. Reduce the icon size slightly the further out you zoom so stuff isn't as cluttered in the late game.
This idea isn't specific to your mod, it could be used anywhere, but it might make for a nice feature/addition if you think it's worthwhile.
@arran Thanks Arran! Glad you like it!
Haha my LEGO-navy icons, as I like to call them. My favourite detail must be the legs on the Salem 
Next release is coming any day (or week) now actually!
- Overlays will be optional checkboxes via UMT options menu.
- Every base game unit now has an icon, some have been updated slighly for better consistency.
After uploading the beta I realized I was in the middle of trying some stuff with the factory overlays, so yeah that's my bad. They will be working in V2. For V3 I'm thinking of having the icon change depending on what is currently being built, like when building engineers now. But color coded this time - of course.
About the shields, I am not sure what you are refering to. I haven't had any problems with them. Could you elaborate a bit, or if you have a screenshot?
Feel free to try the current version, maybe it's something I have solved unknowingly. I would also gladly hear your thoughts before the release:

I am totally up for ideas on the design. As is evident from the experimentals, I am no Picasso. Maybe they should not be depicted at all like now, instead just some generic symbol? Spider definitely deserves a cool icon (not that I am biased towards Cybran or anything.. 
)
The size/zoom thing, I have thought about it too. I don't think it's possible to solve unfortunately, for the same reason many icon mods have 1080/1444/4k versions. Everything is pixel based in a specific format, so they are not intended to scale. It might be possible to create a new set of smaller icons, and load dynamically on certain zoom breakpoints. If anyone knows some limitations here please let me know. Realisically this is a V4 feature at the earliest.
Yesterday I discovered that the shield issues are somehow related to the bloom setting. With bloom off, the shield icons look normal, but with bloom on, the icons look whitewashed (i.e. white squares), and you cannot see the blue(ish)/purple square part of the icon. Sadly V2 still has this problem for me.
Top is with bloom on, bottom is with bloom off. 
Disclaimer: This issue with bloom is being exacerbated by one of my other UI mods (I think). But even with all my other UI mods disabled, the issue persists, just not nearly as noticeably.
I do wonder if this might be a problem on my end or not since the factory overlay isn't working properly either. If you can get other people to give feedback, that would be of help.
Disabling every mod except Color coded strategic icons sadly didn't get the functionality working. Your code was also too complicated for me to understand!
In V2, the engineer overlays are much better, especially in regards to the SACU icons. A small suggestion might be to only have the nuke/antinuke overlays appear after they have finished construction? IDK if this is feasible or not to do.
I'd also suggest adding UI Mod Tools (uid = "ui-mod-tools-4z0t-v12") to the required mods list in the mod_info file. People might otherwise complain that the mod is "broken" when they've forgotten to add the dependencies.

Unfortunately, so far as designs go, I'm no artist either! The best I can do is spot asymmetry in icons. Like with the T2 PD, T2 AA, T2 TMD, T2 radar, T2 sonar. And in this regard something weird is happening. In the dds files, the images are perfectly fine, but when displayed above a structure, they are slightly shifted.
I also noticed that the mass storage icon (all except _rest) still uses the Redux Strategic Icon while all the other icons (so far as I can tell) all have unique icons now.
For experimentals it's hard. Honestly, they aren't too bad in their current state. My only suggestions would be to reduce the size of the Ahwassa icon size to be more in line with the other air experimentals, and to increase the relative size of the depictions of the GC, Chicken, et cetera inside their red circles to make them more clearly distinguished.
Also the Neptune has a little blue strip at the top of it's icon indicating anti-air capabilities, yet it has no AA.
Hopefully this feedback helps!
P.S. SMD overlay caps at 5, not 7. I also saw some code to have the number be replaced by a "+" when over some number, but that doesn't seem to be working/implemented yet.
@arran Good catches!
The asymmetry is actually present for all icons. It seems as if its the surrounding glow that gets cut off, on the inside of the glow not the outside. Very strange. Any attempt of mine to mitigate it by changing the icon only makes it worse. When changing colors through the "use team colors" or whatever it is called, it's displayed more properly. Red works bettar than blue for example. This is the extent of my findings.
Does anyone know some more details of how to work with the icon player color? I just set it to a gray with 70% luminance and it works to show the different colors automatically. There is probably something more to it. What thresholds are used for it to count as a player color for example? Not sure where to find info on exactly how it works.
That I havent noticed the bloom problem makes sense since I am going for full performance settings (ie my computer is slow). Will experiment and see if I figure something out, but without that other mod I take it that it is still showing as purple then. I am guessing the only solution is to change the color, to something darker perhaps.
Only showing overlays after building is finished. I tried self.unit:IsBeingBuilt(), but get error: attempt to call method `IsBeingBuilt' (a nil value). Will do some digging.
I actually didnt add UMT as a required mod for two reasons, 1 it can work without it so didn't want to force anyone to download it, and 2 I guess if UMT is updated this will cause a problem. I don't think there is any dependancy management like UMT >= 12 to solve the issue. But UMT is pretty standard and I can always update my mod with new dependencies whenever there is a new UMT release so I will consider it!
Thanks Arran!
V3 is the bees knees! Very cool and love it. Thank you for taking my suggestions on board and for taking the time to fix EVERYTHING*! That can't have been a small task. Seriously impressive stuff.
There is one major problem with your mod. Whenever I look at a YT cast of a game, I feel blinded by the obscurity of it all. Everything morphs into one indistinguishable blob. Totally wrecked my enjoyment of watching FAF casts
*Those idle factories and their grey outlines hovering on top of other icons is a little janky. Also SMD can't count to 7 haha.
@arran Ah! That's right, I forgot the SMDs! For V4 they will have graduated from elemantary school, promise!
Casts, I know.. sorry about that 
You know what, I will write some YT comments and ask if they want to try it!
