Good start Rated 3 out of 5 stars
Smooth scrolling. A couple of features missing to become a must have.
Lacking An Always On Mode Rated 3 out of 5 stars
There should be an option to always use left, right or mouse middle -button as panning hand!
interesting Rated 4 out of 5 stars
Why not just make control + left click do the dragging instead of the enabling dragging mode thing?
