I have many accounts per platform, so I have MANY pinned (permanent) tabs. Unfortunately, these pinned tabs take up all of the available space to display the unpinned (temporary) tabs. I have been searching for a way to isolate the Pinned tabs under their own dropdown menu, or some other method. I believe the new sidebar and vertical tabs could be the solution (especially once you add the "Expand on hover" option. Please provide an option to have Pinned tabs appear in the vertical tab orientation in the Sidebar, but leave the Unpinned tabs in the standard horizontal layout.
