I'd love to see a new tab or button up in the header that links DIRECTLY to the default theme admin screen. I was working on a site last night and having to go back and forth from the module manager to the admin screen for the template got REALLY old. I know I could probably make a short cut on the dashboard, but then I'd need to revisit that page all the time.
So, consider this a feature request to implement something similar to what you've done in the WP templates where there are shortcut buttons to take you between the widgets screen and the gantry settings screen. Either in the header somewhere or at the least, somewhere on the module manager screen. Sure would speed things up
