As a board user I would like to be able to quickly change the Swimlane configuration without having to go into the board configuration screens. Just offering the more simple choices would be good, Epics, Assignee, Etc., leaving our JQL would be fine.

We like to have the Swimlanes by Stories most of the time and then use quick filters to show issues for a particular user. However it would be more useful if you could just switch to By Assignee or Epics more quickly.
