Support multiple namespaces?

Should we support multiple namespaces? How should this look like? I don't think we can put multiple icons in the tab bar.

We can use a list with multiple namespaces and the user has to select a current namespace in the preferences. I think multiple icons aren't a good solution.

Yes, we could provide an option in the preference dialog, but I'd like to be able to use multiple namespaces simultaneously. However, I am not sure if we can come up with a solution that has a decent usability.
