Excelent script. Actually i do not use all of its features (calendar, memos, etc...). But if you work from several computers (home, work, laptop) then it realy helps you to access your bookmarks anytime/anywhere.
No need to manualy sinchronize bookmarks/favorites between computers (no regular export/import).
You never forget to save favorities when reinstalling OS to your pc.
Of course, it would be nice to setup regullar backup of database;)
