When I'm looking at my tab list in Tab Overview, I would like to be able to have the same right-click menu available for tabs as what I get by right-clicking a tab on the tab bar. This would make it really easy for me to move tabs to new/saved windows, bookmark them, reload them, etc.
Being able to move tabs to new/saved windows would be especially helpful for organizing a window that's gotten out of control. For example, I have a bunch of tabs open in "normal"/un-saved windows, some of which I want to keep, and some of which I don't need anymore. I want to go thru them in Tab Overview, move/bookmark the ones I want to save, and close the ones I don't need. But there's currently no way to move tabs between windows directly from Tab Overview (that I can see).
