BTW, are there any advantages to use the "bookmarks system" instead of favorites
How about our favorite topic - tagging. I use tags in the description field so one can find bookmarks irrespective of their title/URL. Quick find using the bookmark panel [CTRL]+3
And have you ever tried SHIFT+F2 with bookmark nicknames. It autocompletes on the nickname, so if you have a unique nickname "HUBA" you simply type:
[SHIFT]+[F2] -> "HU"
and you will go to the page as soon as enogh characters are entered to make it clear which nickname you want, no need to press enter.
And I prefer having a simple text file compared to a pseudo file-system directory structure for backup and manual conversion via scripts etc.
