Here we go:
to restore the undo history of the last closed tab we need to keep it
in memory somehow, this also means we need to get it from Scintilla and
then on restoring we need to get it back into Scintilla. There is no
such API for that, AFAIK. So, we would need lots of new code in Geany
*and* in Scintilla. Or we would have to keep the whole Scintilla object
when closing a tab.

The above is only for *one* tab and only for the undo history, not to
mention saving/restoring symbol list state, folding state, selection
state or whatever.
Jerome even requests this for many/all files and want to save it even
on disk between sessions.


Some time ago, there was a similar discussion[1] about saving things
like cursor position, selection state and more not only for session
files but for files in general. One solution how this could be solved
would be to use xattr and similar techniques or some kind of database
which stores metadata for each files which was ever opened in Geany (and
maybe with some cleanup mechanism).

I don't want something like this in Geany. If anyone wants to write a
plugin which implements any of the above mentioned functionality, this
is completely ok and cool.
