A few in game UI suggestions - Unit Selection Indicator and Units Waiting to be Deployed Indicator
I'm not sure if this has been brought up yet but two things that have currently been a bit annoying with my games has been the unit selection indicator and also not knowing when units are ready to be deployed.
The unit selection indicator is rather simple, I just feel like it's hard to determine which units I have selected due to the health bars being in the same circle. I can see the design attempt there but for me personally it just gets a little bit confusing.
Also on that the similarity in color between the health bar and the weapon cool down bar makes the whole thing difficult to for me to distinguish the two.
The other thing that I feel could be beneficial is that whenever units are done building and are ready to be deployed, that there be some indicator somewhere (probably on the upper left box) saying how many units are currently waiting to be deployed. I find my self constantly in game not hearing or remembering if I heard the "unit completed" sound notification and going back to my base and spamming V to see if anything can come out because I have no way to know and I forgot if I heard anything or not. So I think a "units waiting to be deployed" indicator would be beneficial to increasing efficiency of macro.
