• feature request: merge duplicate folders (case insensitive)
• feature request: find duplicate URL's (Seemingly bookmarkdupes only finds duplicate title's, unless i'm mistaken)

1. Won't happen: Bookmarkdupes is specialized for deleting bookmarks only, not for re-organizing
2. bookmarkdupes detects duplicates only by URL. Only in expert modes, you can do some tricks like replacing the URL with its name for the comparison.
