Ahh, I can breathe better already :) Speaking of the gallery (this is
getting OT for ipython), I think it's in serious need of a cleanup. I
appreciate today's PR on organizing it by sections, but the real issue
is that over the years, the gallery has accrued a lot of scripts
without any comments or explanations of purpose, deprecated APIs, etc.
I wonder if you could spur a 'gallery cleanup' project, encouraging
users to submit pull requests that remove duplicate/similar examples,
document better the ones left, etc. While there's a lot of good stuff
there and I continue to point people to it, there really is also a
massive amount of weed growth that is starting to be annoying in
But the cleanup job is easy, can be done by non-experts (and is hence
a great one for new developers to start contributing) and would be
very beneficial to the project at large.

Yes, that's really one thing it's great at. And by purposefully
controlling explicit references to your axes, you can do the buildup
incrementally. And the '>' "play" button in the new UI is great for
demos, as you can by and large run a demo just by clicking repeatedly
on that button. I've been quite happy with that pattern.
