I'm wondering if there's a way to save window configurations across emacs sessions. I know desktop-save is fantastic for preserving buffers and whatnot and the emacs manual demonstrates storing a window configuration into a register but this doesn't persist across sessions.
Of course this doesn't seem like it would be too hard to implement myself...
EmacsWiki is a great resource: EmacsWiki: Session Management
Looks like Windows Mode, or more specifically revive.el, is what you want.
