Hi
The feature request Bookmark Bar shortcut I think was written before or shortly after the addition of the sidebar to Brave; The bookmarks folder is actually included in the sidebar, it is the second folder from top. One can also add individual links to it. But it would have been nice if the sidebar is on the right side!
For me the ultimate browser is the one that gives us the possibilty to toggle on/off the bookmarks and URL bars -when hovering the mouse at the top of the screen- all this while working fullscreen! A dream request for Brave!
