DrawIt is an interesting image editing application that sports both layer support and vector tools, plus a very intuitive group drill-down feature. It has its own document format, and only exports to , GIF, PNG or TIFF (i.e., no way to get your layered document into or any other app that supports PSD format).

Still, it is a very simple, effective and straightforward way to achieve most simple drawing and annotation tasks with a pretty good degree of control over the final result.

A freeware “lite” edition was released on Feb 2008.
