Do you think it works okay, at least so far as local/federated communities go? What are some adjustments you might like to see to it?
Personally, I still find the dropdown/search combination somewhat unintuitive and at times it can feel clunky, although it has definitely improved. I sort of think a regular search bar to filter through communities/posters might be better, with a separate dropdown beneath or next to the bar, so one knows one can directly search by community/username, but I can see why it was done the way it was to a degree.
Works great for me!
