As much I love using Brave, recently I lost all my Extensions, Bookmarks, History and Settings after restoring my Mac from the iCloud Backup. Apple restored all the apps however I got message from Brave saying some setting could not be restored. I see the Sync feature but this is a very manual process.
It will be good to introduce some kind of automatic backup of the Bookmarks and Settings like Chrome do. To make it more private and secure we could use Dropbox Sync like 1Password do. I could select my own private Dropbox account and the file could be encrypted.
