[Pharo-dev] Alternative window manager

Hello, Does an alternative window manager for pharo exist? For some reasons I always end up with a tangled mess of windows when using the default one. My biggest gripe is that new windows tend to open on top of other windows, blocking the view even if there is still empty space elsewhere. I watched this video ( https://www.youtube.com/watch?v=Wx0eNaGzAZU ) about the i3 window manager for linux and how it paves the screen with the windows to optimise screen space and make things look less messy, and was wondering whether something like that existed for pharo. Cheers, Thomas
