Hey Steven,

That sounds fantastic!

I've tried to make a pretty solid API for the viewer, but since I'm the
only one playing with this code (as far as I know), it's tough to know
whether any of the infrastructure makes sense. It'd be great to have
someone else around to kick the tires and tell me what I did wrong.

As far as your suggestions, they all sound great. The "cross section slice
view", however, sounds similar to the lineprofile
plugin<https://github.com/scikit-image/scikit-image/blob/master/viewer_examples/plugins/lineprofile.py>that
Guillaume Gay wrote, so you may want to check that out first. I've
been wanting to add some sort of menu interface to access the plugins, so
it'd be great if you already have something. Also, I think the ROI stats
viewer would be a pretty good example of the RectangleTool added in this PR.

I'm looking forward to seeing some more PRs from you :)

Best,
-Tony
