    I also use desktop.el, and have for several years.  It is primarily
    focused on saving the list of buffers with their files, directories,
    point and mark and various buffer-local variables.  If it can
    save frame configs I haven't seen how to do it, but perhaps that
    would make a good extension...  If I have some more time to spend
    on this perhaps I will give it a try.

Sorry about misleading you. I don't use desktop, and I thought it restored
frames too (they are part of the "desktop", no?).

If you do extend desktop.el to do that, think about making that an option,
as some people might want to turn it off.
