@julian That was it.
I had an older version of the Lavender theme with the old style admin template.
I'm pretty sure that very little minification occurs when the templates are processed, and figured this would be one place of possible improvement.
I was going to make a fork and then modify stuff, then make a pull request, (If that's how it's done, new to git stuff) but I wasn't sure where the stuff happened. Was also going to work on the documentation eventually.
Good work BTW.
@pitaj check out the templates.js repository that is the templating engine we use.
