When I create a new bookmark, sometimes I realize I don’t have a fitting bookmark group for it to place it into. This happens not before I start bookmarking, but when I already study the list.
Add a new item in the ‘Bookmark group’ dropdown list at the very bottom, ‘New group’. When it gets chosen, add a new field below the dropdown, so a user can enter the name for the new group.
So far I have to create a bookmark in the root, then go to Bookmarks, create a new group there and move my bookmark. This is slow and irritating.
