I have multiple hubs and it would be nice if the web interface allows for viewing and connecting to my other hubs. They are even in the same mesh. Maybe a section on the top that shows icons for each hub (can even be model-specific) and some sort of health indicator.
I would imagine some people will be augmenting their existing hubs with the new C8pro+thread-radio and so it will be more common to have multiple active hubs.
