Chrome Extension: Resolution Test


I was just thinking about creating a background for my Twitter page when I thought it would be useful if there was a chrome extension that would resize your window to mimic different display resolutions. I did a search but I couldn’t find one, so I thought I’d have a go at creating one myself.

I haven’t done a lot of javascript before and its still very rusty, but if you’re running chrome on the dev branch you can install the extension here.

Enjoy :)
