For now, we have a batch hotkeys to select engineers, the one of them is "Select engineers on screen". It is very handy for low-apm noobs like me, to not try double click engineer to call this action, but press a cool hotkey.
I have a same settings for land, interceptors and sea. This is really cool stuff.
The issue with engineers hotkey is what it selects ACU too. I think this is no-sense behaviour, yes ACU have engineer suit and technically it is an engineer class entity. But in real use cases ACU is an ACU and when player wants engineers, he wants THE engineer, not ACU as engineer.
Also, player what use "select engineers hotkeys" most likely to use "select ACU" hotkey.
So i purpose, to change "Select all engineers on screen" to "Select all engineers on screen (Except ACU")
