Windows management

What I'm wanting to do is have some kind of windows management(FM windows, not the OS). I'm building a solution that takes advantage of the multiple windows feature that started with FM7. I'm wanting to do things like - remember last size/position for each window for each user, run script upon window exit, resize window based on screen resolution/zoom, position a new window based off an existing window's position etc...

While not really "necessary" to have these features, this solution is a 'shrink wrap', so users would certainly like it.

I know that this can be done, but I can save myself a lot of time if someone else has already come up with these ideas and how to best implement them. Any help would certainly be appreciated.
