Thanks for sharing this feedback with us, @MarcGarcia! As a workaround, to be able to create sections in your Favorite bar, you can create a fake project called “------Current Projects------” and mark it as favorite. This project will appear in your favorites and you will be able to move projects under this section to separate from the others.

We don’t have immediate plans to implement this feature but I’ll keep you posted as soon as we have any news!
