Is there some sort of session management?

[Thomas Wehrspann]

Hi,

Openbox is a great windowmanager with nearly all features i need.
But one is missing? Is it possible to store/restore the position of windows 
on shutdown/startup of applications?
The only thing i found was this statement:
-------
   allow for 'session management' of a sort. let the wm remember a window's
   position/size/other attributes if they are saved by the user (window menu
   or something). this is especially important for dockapps to be cool
-------
I'm using a Xinerama configuration with Openbox. Very minimalistic.
No Gnome, KDE,... and i like to avoid GTK2 for the moment as well.

Is there something like this on the way or already in place?


Thanks in advance,
