The suggested tags is what I'm really interested in, but don't want to pay extra for it. It'd be nice if a Chrome extension (since my bookmarks are sync'd there anyway) handled this with a nicer display but used the existing bookmarks.

For example, a tag of the subreddit would be excellent for all my recent /r/unixporn inspiration saves. Managing bookmarks is a hassle and why I usually don't bother or throw them into a "Misc" folder.
