My current setup is im running ubuntu core with blackbox as my window manager. I am running dual screens and am having problems with where my windows open. They always open in the middle of the two screens, but i want them to open where they were last closed. Does anyone know of a program that does that?

- Manages window placement
- remembers where windows were closed and opens them in the same spot

I know of Devilspie but that always puts the window in the same place. And is a little akward to get working with multiple programs.
And i tried using blackbox's window placement uttilities but they are very restricted

thanks
