I find this a bit pointless. The site is good as it is and adding more features like this would just clog up the interface.

I don't see this feature as an absolutely necessary but rather as a good-to-have for some advanced users.

I would recommend to use your browser history for that purpose. Does the job perfectly for me. Just use "`superuser.com`" as a filter and you will get your most recently visited pages.

You can also look at improving your browser history with one of the existing addons. For Chrome addons see https://superuser.com/q/352970/281154
