My main problem mainly is that I upgrade a mex early on, then see I have mass, select more mexes and smts select the upgrading ones as well by accident cuz I bind my first mexes to the hotkeys 3-5. -> T3 upgrade queues without me noticing since that takes 1 second. So that problem (at least for me) still exists but could be that it's just a thing I have to get used to now
Split mex t2/t3 upgrade hotkey
I made this mod that prevents mex's from double upgrading. Might help solve the issue.
What's it do exactly? Prevent queueing the next mex upgrade?
Yeah just looked at it, that's what it does.
Still seeing lots of accidental T3 mexes deciding high level ladder games. It will be a problem perpetually since most of these people aren't active regularly so there will always be people coming in that are not adjusted to the change, and do not know it was made.
Similarly, hotbuild seems to have been made a bit more finicky with switching buildings so you can often make accidental air factories or other things.
It is pretty criminal to be constantly changing the UI of a 17 year old game and messing up everyones muscle memory. Many prominent members of the community are inactive for months at a time, and each time they come back there will be different random UI quirks and new stupid features that are enabled by default, along with a new group of UI mods that were broken and have to be replaced.

This was reported and fixed, will be shipped with the hotfix of tomorrow.

Usually these are accidental. We're open to feedback, but we can't process feedback that we don't have 
A work of art is never finished, merely abandoned

"Keep the game fresh otherwise FAF will slowly die"
"No, not like that"
You can't win
Pretty big difference between changing gameplay and changing the UI and controls.
It is clearly a deliberate choice to add new UI things like automatic mex selection with cursor, auto-ringing, reclaim batching, changing upgrade key behavior, and it's a deliberate choice to enable them by default. And it has the side effect of breaking UI mods people have been using for a long time.
It creates a barrier for any player returning from hiatus since they have to go through the interface options and mod vault trying to restore the UI to how it was when they last played.
These things would be good changes in a new game, or in development game, but it's not great for an ancient game that people just come back to from time to time.
I think with faf-develop being played so little, there are always going to be bugs that slip through and you can't fault the contributors for that, especially when they are quick on getting the fixes done once issues are identified.
Ideally we find some to encourage it to be played more - and also a way to avoid downloading the regular game files when going back to normal games.
for intentional changes to actual ui behaviour these should be defaulted to what you currently have in your game.prefs however.
