Support! Definitely, I have 3 pages of bookmarks that I sift through almost everyday. I often bookmark topics I haven't posted in, just to keep an eye on them, and sometimes I can't find them through the many bookmarks I have. It sucks going through the scare that I never bookmarked it in the first place.
Even yesterday I thought I'd lost an old topic and ended up looking through 10 pages of search results in a thread just to find that I actually had bookmarked it.

Just me? xD
