Middle mouse scroll to change values:

[avclubvids]

I find myself constantly wanting to be able to hover over a control and use the middle mouse wheel to either scrub a slider, scroll through items in a dropdown list, or change a numerical value. It's a super fast way of quickly manipulating a UI, it'd be boss to see it in Fusion.

Oh and Nuke users are going to really miss being able to up/down arrow key to change a selected numerical value, with left/right changing the decimal place. And I'd agree with them - it's a super fast way to nudge a value to get where you want.
