After I was orphaned from xMarks, it replaced it nicely.
But the only caveat is that when I do a search on a bookmark that is duplicated, it simply shows the 2 (or more duplicates) without telling me where it is located, in which subfolder they are found, making it difficult to organize them...
In the bookmark popup itself, it could show in which folder the link is located.
Fix this, and me and the rest of the guys will give 10 stars
