I'm currently playing with the tagging branch and I've managed to reduce the tagging code to two modfiers. I'm using Ctrl+A + {1,2,3,4} for view, Ctrl+A + {!,@,#,$} for tag (so it mirrors dwm's keybinds a bit). I'm also using Ctrl+S + {1,2,3,4} for toggletag and Ctrl+S + {!,@,#,$} for toggleview. This replicates tmux pretty well for me, so I'm a pretty happy camper with regards to this portion. However, I've noticed that screen drawing seems... wonky. (particularly with vim) I have installed the 'new' terminfo (not sure if it changed; didn't think to check till now...) to no avail. Was some of the redrawing logic that was changed in 0.11 changed in rebasing tagging onto master?
I'm also not 100% clear on what toggleview should actually DO. 'view' brings a tag into view (and discards any other tags from the view) 'tag' "sends" a client to a tag (much like "send to dekstop" does in most wms) 'toggletag' brings a tag into your current view. 'toggleview' doesn't seem to do...anything.
