My dream of tab management is if the browser would suspend long-unused tabs into a tree-style list—i.e. a bunch of bookmarks in the same arrangement in which I opened the tabs, without overhead of actual tabs. Then, live tabs could also be on the same list. Right now, suspended tabs in FF still take memory and slow the browser down, and are cumbersome to search through. Basically, I'll need to marry Tab Suspender with Tab Session Manager, then perhaps borrow the UI of Tree Style Tabs.
