Hydra definitely sounds nice, but unless I'm misunderstanding how it
works, it can't be a replacement for either Org's export interface, or
Magit's popups. Both of those can set various state variables before
choosing an actual action -- Hydra can't do that, can it?

Did I hear that Magit was breaking its popup interface out into a
separate library? If so, that would also be a nice thing.
