That might be true. For me Paw's UI doesn't help me (a simple user vs a power user) to work pleasantly. I am forced in Paw to deal with Projects, difficulty to rename requests, etc.
And, if it helps, you can rename a request in Paw by clicking on its name in the sidebar while you have the request selected or clicking on the name where it shows up as a title in the Description panel in the middle of the screen.
By the way, you can double-click a request to rename it :)
