Avoid interference between projects opened in the same Pitivi process
Until recently, the first toolbar item was a "<" that lets you go back to the welcome dialog, which lets you create a new blank project.
It might make sense to bring back at least the "New project" action as a menu item in the hamburger menu? It's fairly practical for testing purposes, vs having to quit and launch Pitivi every time.
