Last time i made some changes to hotkeys not everything was received as well as i thought it would.
Therefor i'll just ask for feedback before i change more stuff that people might not like.
1: Colors
The hotkey labels have different colors depending on the what modifier key you use.
white = no modifier, red, yellow and orange for CTRL +ALT, CTRL or ALT respectively.
I find the current colors to be kinda terrible especially since the yellow is hard to distinguish from the orange - at least for me.
In the 2nd screenshot the colors are changed to blue for CTRL + ALT, red for ALT and green for CTRL.
Spoiler: show
2: selecting all naval units:
Currently the select all naval units does select T3 sonar with your navy since it's technically a naval unit. I find that sonar shouldn't be moving around too much especially together with your naval fleet it shouldn't be selected by that hotkey.
