Itinerary?

Bad name for it.

I tend to open a page and then open a number behind them with the intention of reading them later and, unfortunately, I usually don't get to read everything I want to read by the end of the night. And I want to close my browser and shut down my computer. The easy answer is to bookmark what I haven't read yet, but I don't like that. They usually just clutter my browser by staying there forever, unlooked at. I want to be able to store unread links over to the side, in some sort of itinerary, so I can just check and uncheck it like mail so I can look at the things and, when I'm done, they go away.

I'm sure there are options for this, but I'm looking for something very specific.
