If I'm spending days at a time on a workboard as a PM, I might just want to favorite the fullscreen version (given upcoming sidebar changes).
Currently the workboard has an option for fullscreen display. However this setting is lost when the browser refreshes. Since we're using Chrome + a Chrome autorefresh extension (SuperAutoRefresh) to display a Phabricator workboard on a bigscreen TV it would be useful if this setting is persisted across refreshes. Like ?fullscreen=yes as suggested.
