You can save the window configuration of the selected frame in a register, or even the configuration of all windows in all frames, and restore the configuration later.
Use C-x r j r to restore a window or frame configuration. This is the same command used to restore a cursor position. When you restore a frame configuration, any existing frames not included in the configuration become invisible. If you wish to delete these frames instead, use C-u C-x r j r.
