I would be nice if you could select skills from the skill page instead of having cast them from the skill bar. Some of the trees have very situational skills that don't get used that often and most games I end up having more skills than slots so I have to switch the skill on the bar, use it and then switch it back. It would be similar to how you can use stuff strait out of your inventory like arrows and potions without having it in your belt. Its pretty minor and not that big of a deal but it would be pretty easy to implement I imagine.
