This is probably a 1%er problem and therefore not hugely necessary, but nonetheless…
The green plus indicator lets us know when we can trait the troop. Works as intended, very well. What I’d like is if this was modified to show us how many traits we could afford on the troop.
To facilitate this, I would suggest (for example) having green pluses in the same spot as the little trait banners on the upper left side. i.e.
0 traits, can afford 1 trait, first slot has a plus.
0 traits, can afford all 3 traits, all three slots have a plus.
1 trait, can afford another 1 trait, first slot has the trait banner, second slot has a plus, third has nothing.
Etc. Or they could be Purple -> Orange -> Cyan pluses to match the banner colors. Who knows.
This also means the green plus can be (not necessarily should be) removed from the top-right corner, where it currently has to share space with the blue arrow of ascension.
