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?
