Scene tab > Position > Rotation fields:
Using the up-down arrows or mouse wheel, the Rotation changes in 45 degree increments. I don't know of any short cut that overrides this increment.
I would like to see smooth rotation in 1 degree (or less) increments, with 45 degree jumps only when holding down a key. To me that would be more consistent with the way I see the UI work in other graphic programs.
The position tool is great for getting close, but sometimes going straight to the Rotation fields is necessary to fine-tune the position.

Thanks - we will take this into consideration.
