Consolisation, yay.
In PC RPGs, no inventory system should be anything else than click and drag, icons, and such. I shouldn't have to cycle through windows or lists or horizontal running menus that spread beyond the one screen. One screen that shows everything I have. Yay for little squares a la Diablo. Morrowind had a better inventory than Fallout New Vegas for the PC for christ's sake. I want to see every option and clickable thing in one screen, and I want to drag and drop.
Yay, the constellation is pretty and all, but by now, shouldn't be easy to just have all skills listed on one screen withouth having to drag the screen around as if I were looking at album covers on itunes. For that matter, I never use that viewing system in iTunes: I use the one where i see as many albums in one screen as possible, not the rolling album covers display. Ugh.
