Super simple suggestion!
I often find that I can’t move the pitch accurately enough with Shift/Left Mouse drag. It seems to jump 2% or perhaps 4% but rarely 1%. Could the Current Pitch field be made editable? Then it would be easy to dial exactly what’s needed straight into place.
Also the Reset option which is currently buried on the left side control panel could also be here between the two fields. It would return any highlighted events back to Original Pitch by copying right field into left.
