So if you swap to another server, the dashboard needs to re-query the server, if it is enabled. I am not sure what you would do if, one server has it enabled and the other doesn't. Maybe pick the next active service on that server.
If I am looking at the dashboard calendar and swap to another server, then the dashboard calendar needs to refresh automatically on server change. At the moment it seems to refresh only if I press the dashboard icon on the menu listing services set up on the server.
Since I can change a server and the press the part of that screen, which forces the main menu slide back to the right. Which means I am still looking at the calendar of the previous server
