Is there a way in Firefox to color code the Bookmarks by usage like Disk Defragment software does with file usage? I would like to see Bookmarks color coded based upon their usage. The most visited ones would be color coded green, the next most frequent group yellow and those not used within the last several months would be color coded red. This way it would be relatively easy to decide if you want to delete an unused Bookmark. It would be even better if the user had the option to delete all of those Bookmarks color coded red or at least move have them all moved with just one click into a folder named Rarely Used Bookmarks. From there the user could either delete them all or just specific ones.
