There’s an nice new screenshot annotation feature built in to the latest version (3.5) of Droplr. It lets you add arrows, circles, rectangles, text, and freeform scribbles onto any screenshot and then upload to Droplr with one click. It’s a more streamlined workflow than what I’ve been doing with the old Skitch app.

Note that the Draw feature is for Droplr Pro Subscribers only.
