+Q: Why does Metacity remember the workspace/position of some apps
+ but not others?
+A: Metacity only stores sizes/positions for apps that are session
+ managed. As far as I can determine, there is no way to attempt
+ to remember workspace/position for non-session-aware apps without
+ causing a lot of weird effects.
+ The reason is that you don't know which non-SM-aware apps were
+ launched by the session. When you initially log in, Metacity sees a
+ bunch of new windows appear. But it can't distinguish between
+ windows that were stored in your session, or windows you just
+ launched after logging in. If Metacity tried to guess that a window
+ was from the session, it could e.g. maximize a dialog, or put a
+ window you just launched on another desktop or in a weird
+ place. And in fact I see a lot of bugs like this in window managers
+ that try to handle non-session-aware apps.
+ However, for session-aware apps, Metacity can tell that the
+ application instance is from the session and thus restore it
+ reliably, assuming the app properly restores the windows it had
+ open on session save.
+ So the correct way to fix the situation is to make apps
+ session-aware. libSM has come with X for years, it's very
+ standardized, it's shared by GNOME and KDE - even twm is
+ session-aware. So anyone who won't take a patch to add SM is more
+ archaic than twm - and you should flame them. ;-)
+ Docs on session management:
+ See also the ICCCM section on SM. For GNOME apps, use
+ the GnomeClient object. For a simple coding example using
+ libSM directly, twm/session.c in the twm source code is
+ pretty easy to understand.
+Q: How about adding viewports in addition to workspaces?
+A: I could conceivably be convinced to use viewports _instead_ of
+ workspaces, though currently I'm not thinking that. But I don't
+ think it makes any sense to have both; it's just confusing. They
+ are functionally equivalent.
Q: Did you spend a lot of time on this?
