It would be good to have a possibility that any user could set an agile board (available for everyone) as default just for him\herself.
If a project has lots of teams and each team wants to have a shared board available by default just for them. Each department (even without people plugin, just the number of users) could see a board that was specifically designed and shared for them without looking for it in a list of boards over and over.

Nice-to-have feature
