A document viewer with autosave tabs

Given the window management and controls, Evince is a major outliar in OS luna, as each document is opened in a new window, and the toolbar is different from other apps. This can make window management harder to work with - especially with no apperent minimize button, as well as the fact that document viewers are often used alongside other apps. In the next release after luna, a tabbed viewer would work much better - and perhaps it could open up the last tabs you used, like in Midori.
