Favorites/Pinned section

I think it would be great to have the ability to pin some requests as favorites. It would make them appear at the top of their parent folder (or workspace if not in a folder) with a little icon (star or pin ?) and in a section that would be on top of the sidebar (and collapsible of course)

I think there could even be a feature (optional) to allow this section to also display the most frequently used requests (with a little clock icon for example).

In the case of a pretty heavy API, this would allow to keep things organized (like a folder for each namespace) while keeping quick access to the most used requests.
