In dwb, there is the "quickmark" feature, which lets you associate a few letters to a link. You can access them by pressing b (open quickmark) and then type those letters. This forum is marked as "nx" for me for example. So when I want to save something, I mark the page with a quick word, so I can easily come back to it.

Vimb also has this nice feature which is the "read it later" queue. You push link to a FILO list, so you can save the URL until you read them. This is a pretty cool feature which COULD make me switch away from dwb. But vimb has no tabs...
