I really like how the scroll wheel scrolls through your spells. I would love the same ability to scroll through my belt of bolts, potions, etc. Using Shift-Scroll makes the most sense since Shift-# it what selects those slots.
...wait, scroll wheel scrolls through your spells? Does it also go through your non-equipped spells? Because that'd be amazing.
Yes. No. Something definitely needs to be done about non-equipped spells. They need to be easier to access.
If nothing else we should be allowed to right-click an unlocked skill in our skill book to select it. We can't even do that, we have to swap out some other skill we're using. I regularly hit the point where I've got more than 10 skills I'd like to use before DL 5.
I admit to playing warrior-types 90% of the time, so this rarely comes up for me. However, I've definitely thought about it and something needs to be done. The simplest in concept is to simply allow clicking spells in the skill list, but I have no idea what it would take for the UI to allow that.
I did not even know the scroll wheel did anything in the game. I use numbers and shift+numbers to select anything. But I support this as a future addition/UI change.
Be assured this behavior (scroll wheel acting weird, like left click) isn't intended and is still on the todo list. I don't know about actually scrolling through skills though, but I'd personally like that as well.
