I'm glad you like it.

I just added another tool: A canvas painter. It's a bit less responsive
than I'd like, but I think it's as fast as it'll get (it's limited by
matplotlib's blitting support for images). Check out the watershed demo in
the `viewer_examples/plugins` folder, which uses the paint tool to generate
markers for watershed segmentation.

Best,
-Tony
