Few Suggestions... Rated 4 out of 5 stars
Need the ability to:
-Change Icons (default set is good but generic)
-Change Names (even without change of icons name change would be good for usability)
-Organize bookmarks into folders based on the tags applied. (Graph tagged bookmarks go into bookmarks folder named graphs, not sure if this can be done, cool as hell if it can).
-Change the icons that show first.
Three of these have already been requested just thought I'd keep them on the main page.
With the above features this will become a must have extension.
