Yes, that all seems very comfortable. I can zoom in, adjust notes, draw and delete all very easily without having to remember which tool I need to select or worry about which modifier key to press. It really does free the mind to concentrate on the creative aspect rather than the constructive aspect, whilst editing, I think!
I'd love to be able to zoom and free-pan at the same time...
MMB (i.e. MW on MW mice) double click to restore "default zoom level" (i.e. what clicking the little circle does) might be nice, too.
