Just curious what the advantages are of this versus C-z'ing back to the shell?

EDIT: Oh, I guess that doesn't work in gvim?

It's nice to see terminal output at the same time as you're editing. Right now I'm working on a Rails app, so it'd be great to see RSpec failures while fixing my code--currently I either alt-tab between terminals or use a second monitor.

Also, sometimes you don't want to wait for something. `bundle install` can take a good 30 seconds...I'd rather not watch that!

Thanks for the answer. Seems reasonable. Although at that point I'd somewhat suggest tmux :)
