Feature Request: Folder/directory support for bookmarks

[githubuser1256]

Is there any chance folder/directory support could be added to bookmarks?

The bookmark sync with Nextcloud works great, and now it begs the ability to import bookmarks that are in folders.

In this case, somehow mirroring the standard bookmark folders in the standard Tor Project would be ideal.

I believe there's three standard folders: Bookmarks Toolbar, Bookmarks Menu, and Other Bookmarks.

Perhaps merging of the contents of the Toolbar and Menu folders and remapping the merger to the default bookmark page in Onion Browser could be done since there is no toolbar. In this case, keeping the bookmarks in their appropriate folders when resyncing would still be required. Also adding a bookmark would have to prompt for any of those folders to be chosen.

Alternatively, the rather ungraceful folder names could be kept as-is and just imported.

Thank you.
