Just wondering since it's been a while, is this one still potentially happening?
If this idea cannot happen, or is rejected, how about being able to continuously scroll through the skills, so that when pressing "next skill" once it reaches whichever skill is furthest to the right on the panel, it scrolls back to the skill furthest on the left (and vice versa)? That way, players can use a single pair of hotkeys to easily access all skills.
