This feature is part of the x-tabs branch.

If you want to save frame and window configurations independently of desktops,
you can easily do this using the same functions that desktop.el now uses.

There is a new variable `desktop-save-frame-configuration' that defines
whether to save frame and window configurations to the desktop.
It is nil by default.

It's a separate task to implement named desktops.

I imagine that named desktops should be an object above frames
in the hierarchy of screen objects:

 - desktop
  - frame
   - tab
    - window configuration
     - window

So switching desktops could be like switching frames:

  M-x select-desktop-by-name RET

will read a desktop name, delete old frames by calling `desktop-clear',
and create a new desktop by calling `desktop-read' with the selected name.

Yes, there is a new variable `desktop-frame-parameters-to-save'.
