Request for Enhancement:
Option to lock pinned tabs in vertical tab mode, so scrolling through tabs doesn’t send pinned tabs off the screen.
Optional: Let the user choose whether they should be pinned to the top or bottom, too.
Case:
People often pin tabs because they are not only frequently accessed, but need to be immediately accessible. For instance, you may have VOIP, email, notes, discord, or other tabs which you need to get to fast. Therefore, you want them to always be visible and reachable.
