Comment 14 for bug 391533

This may not be entirely within the window manager space, some involvement with the toolkit may be required too... I do believe this is a genuine problem, and by "passing the buck" and saying that it is simply the applications issue, you are making yourself part of the problem as described by Denny.

The window manager currently has a set of placement algorithms which put windows in logical places on screen... however, Windows has solved this problem with a solution which works very well (better??) in a specific set of circumstances... I would not like to see every window automatically placed where it was before, but it would be a great option to have for certain classes of window (possibly needs an extra flag from the app via the toolkit?)..

For example, within an application, opening a particular dialog repeatedly, you would want the window to be placed the same way each time... certain apps might do well to be restored to wherever they were when they were last used...

I really believe that this is NOT wholly the responsibility of the app, or any individual layer... but it would be good to have a framework for the app to specify how placement of a window should be handled, to allow this kind of functionality to become standard.
