Hi,
Can you add a "tab"  API
Something : possibly via the  config file, that allows extra external tabs to be installed into the main app.
Or it could be as simple as leveraging the list of  current plugins and loading in prefixed ones.. or allowing them to tie externally into the tab infrastructure.

I don't want to submit "tab code" to "github" becasue it don't count as a Umod submission as an author.....
