I just signed up. I've been using and abusing multiple windows and then tabs in Opera's MDI interface since the modem days, when it was nice to have a few pages loading up and come back to them fully loaded instead of waiting for each one.

I'd love to have something indexing and closing old tabs for me in the background instead of manually managing them. Heuristics like 'this tab or any pages on this domain haven't been visited in a week, index the page and close the tab'. At times I use tabs as reminders, perhaps adding some intelligence like "This Kickstarter is expiring in 3 days and hasn't been viewed in a week, you still interested?" might be nice. Any tab with future dates approaching might be worth alerting people to. A summary page might be nice with the last closed tabs, the upcoming dates tabs mentioned above. Pinboard or the like integration would be pretty awesome, that is primarily how I'm managing tabs now.

The more I think about this the more excited I get. Of course the tough part is satisfying each of us who have their own reasons and their own process for managing multiple tabs.
