git clone 'git://github.com/robario/elscreen-persist.git'
This makes elscreen persistent.
To use this, use customize to turn on elscreen-persist-mode
or add the following line somewhere in your init file:
(elscreen-persist-mode 1)
Or manually, use elscreen-persist-store to store,
and use elscreen-persist-restore to restore.
You can use desktop to restore frames.
When desktop restored frames, elscreen-persist doesn't restore any frame.
The behavior occurs when desktop is enabled and desktop-restore-frames is t(default).
elscreen-persist restores all buffers, so desktop doesn't have to save the buffers.
