Right now if a skill is injected, but not trained, it has tiny little blocks (that maybe are white? I can’t tell.) And when looking at ship and module requirements, its nearly impossible to tell if the small dot is one that shows I have it injected and untrained, or not.
Perhaps if the skill is injected they could become hollow-squares that are the same size as the full squares for trained?
Also, perhaps their color could be orange, or purple, or something other than a white that looks awfully like the grey…?
