It would be handy to have a set of pinned tabs for things I frequently use: Unassigned tickets, Assigned to me, etc.
The pinned tabs would open by default on each session, where the not pinned ones would go away.
The not pinned ones would be searches, viewed tickets, etc.
Would also be nice to have a button to close all but pinned.
Additionally, because the width of the tab changes with the title of the tab, and they are left alligned, it would make more sense to move the x (to close) to the left side of the tab, so you can close a bunch of tabs quickly, by clicking in the same place, rather than hitting a moving target.
thanks
