TumblrThemr: Making Tumblr theme development a little less head-desky (tumblrthemr.icelab.com.au)

Awesome ! Leaves you thinking: Now why didn't the folks at Tumblr come up with something like this

Thanks for this!

This looks great - I've been putting off making changes to a couple of themes for ages because of the head-deskyness (the constant cutting and pasting is especially irritating).
