brent these beasts were built for people with 2 screens I think. because after 4 open quadrants (windows) on one screen (that's all I own) it gets small and complicated.
on i3 I use lots of workspaces. I hate multi-monitor setups, although a tiling keyboard-only setup might make it okay.
I'll have a workspace for chat, email and terminal windows, another one for a web browser, another one for an IDE etc.
I assume bspwm does workspaces too? I can't imagine why not, anyway...
