there is a little bug if the sidebar is on the right, its impossible to resize the panel horizontally. if it is on the left, it can be resized normally
would be nice to remove this add button from here and also move the list all tabs button to the vertical tabalso, would be great if possible to customize the items on the vertical tab here
these two last ones are not the same? would be just a new extension on the mozilla store, like adguard or multiaccount containers, simply tab groups, etc
