It would be nice to have a special bookmark folder that would be what you have in the bookmark bar. I have imported about 40 folders from my existing bookmarks, and each folder appears in the bookmark bar when I only want a few links directly accessible in the bar. Is this possible?
Welcome to the forum, sjordi!
Using Vivaldi 1.0.344.5 (Beta) (64-bit) on Windows 10 I don't see any problem doing that. On the Speed Dial tab you just open the Bookmarks and on the right side you can chose 'Use as Bookmark Bar' option for each folder seperately:
Or, in Tools/Settings, go to Appearance and select whichever folder you wish to use as the Bookmarks Bar from the dropdown at the "Select Bookmark Bar Folder" box.
