I agree with having more skills on the skill bar. I like how it currently supports hotkeys (1-9) for those who use the keyboard. Having something like Neverwinter Nights style modifier+hotkey would double/triple/quadruple the number of skills (like Shift+[1-9], Ctrl+[1-9], Alt+[1-9]).
Indeed. It would be even better if the keys could be customized, but 1-9 (or 1-0 or even the keys right to the 0) works really good as time has shown on hundreds of games. The modifier idea is quite good esp. if the skillbar represents the new skillset after pressing the modifier.
