Very useful - Read it later

It puts a couple of buttons on the bar - one is for adding pages to, the other is for reading the pages.

All it really is is a way to dock bookmarks temporarily, but it does it really well. When you get it to show you a page, it pulls it up as usual, but then when you tell it to show you the next one, it deletes the one you just read from the list, so it automatically keeps the list under control without you having to do anything.

Wicked.
