Okay, I do see that `quit-window' has a more complicated job to do, and multiple conditions are checked. I guess I was hoping/expecting that `quit-window' in a member of an atomic window group could somehow be altered to act on the whole group, rather than just the current window. >> This is really helpful, and I see that the docstring of `delete-window' >> actually mentions the case of atomic windows.

I would at least add the fact that atomic groups can be nested, and say something about how to get _rid_ of an atomic group. When I was first experimenting, I ended up having to reboot emacs, because I couldn't figure out how to un-atomic the frame. It would be great to have more examples in the side windows section as well. The two features together feel like they could be very powerful, there's just a bit of a documentation gap. I've had it in the back of my mind to try replacing Gnus' homemade windowing functionality with side windows, because they do pretty much the same thing, but I'm not sure where to start. In particular, the doc examples show a setup where certain buffers appear to _always_ be displayed in certain side buffers. My assumption is that in the vast majority of cases, people would want to display _this_ particular group of buffers in a certain way on _this_ frame, and not pollute the global config. > And if you want a function like the below please tell me. Now that I've seen it, I don't need you to add it :) Generally, the code I've ended up writing for windowing stuff has always been pretty simple, once I figure it out. But some more help figuring it out would be very welcome. Thanks, Eric
