Pie menu for Animation Editors

I recently heard that tab switches between the graph editor and the dope sheet. I was very excited for pie menus being included in official blender, because it's a standard part of my reflexes now when I work. I would love for there to also be a pie menu for the animation editors just like there is for the 3d view. Especially since many of these editors are so important to each other and it's a couple of precise clicks to get what editor you want usually. It would be much easier to just hold tab and gesture to the one you want, in my opinion.

Perhaps this could also be extended to some of the other editors too, as tab and z don't seem to do a lot in most of them
