If I had one enemy commander downvote going into automatch as Soviets, I would downvote this bastard every single time. I'm glad the TA got severely nerfed in a recent patch (but really, how do you miss on something by that far, Relic?), but the whole commander is poorly designed and goes against the spirit of what Company of Heroes 2 should be.
I like the vCoH options for this so much better, having a shield on the side that you could hover over to show all of the unit icons in that group. It meant not having to waste a click on opening/closing the tree and not having it constantly occupy screen real estate when you don't need it.
Personally I never want to close the tree, I like having it permanently on screen to help me track my units.
