You talk about the gui dashlet configuration?
No, the usability patch that I did that was integrated recently (you'll see what I'm referring to if you search my posts). It could have been partly done as a theme, but made more sense as something put in for all themes to inherit.
I suppose I can see your point, if you're very happy with svn, and it's rare for you to easily accept external contributions without a lot of work.
Maybe instead of such a drastic change then, someone here would volunteer to manage the ISPConfig website, make it tidier, explain processes more clearly, install an SVN browser, migrate the issues to a newer system with no data loss, that kind of thing.
