I use Emacs as a single
maximized frame. The monitor is wide enough for two windows to sit together there, with a vertical split. I want this window configuration to be permanent, i.e.:
- I want it to be impossible to delete either of the two child windows (except for by my explicit request or something) and
- I want it to be impossible to split the root window (i.e., add another child, in addition to the existing 2).
IOW, I want it to be impossible to change (add or remove) children of the root window.
How do I do that?
