I use it slightly differently though. I have only a single screen session. I always connect to this session and create new “buffers” in it. Basically in my .bashrc I have “screen -x” which automatically attaches me to the screen session. I have multiple terminals, each with one buffer of the screen.

You should also try out Ion3 (http://modeemi.fi/~tuomov/ion/). It is a tiled and tabbed window manager with non-overlapping windows. You can navigate efficiently through all your open windows using the keyboard (with customizable keybindings). I swear by it!
