I got annoyed with having to run Glitch inside the browser I also use to surf the web. I treat it as a separate app, so I keep trying to tab out of it back into my browser. Luckily I happen to be an owner of the Fluid app, which let's you create "applications" out of webpages. Basically it creates a launchable link to Glitch that resides inside it's own application so you never have to worry about accidentally closing your Glitch tab.
You can download it from my Dropbox: http://dl.dropbox.com/u/6227070/Glitch%20Beta.zip
P.S. it supports full screen mode in Lion!
