Very nice tool. I don't have the patience to fully customise a theme, but i would really like to browse through the existing themes.

The only problem here is that there are a lot of themes (most of them) that were started just for checking the tool out, so they're not really finished or different from the default. Maybe you could add some kind of publish button - or as a quick fix, don't show the themes with "Untitled" in the title.

Otherwise great project. I really think this would be great for medium sized IT shops/companies for branding their tooling. Great job.
