Animator should not open with a projects panel
Character Animator always openes the last project. It takes a lot of time to load a project and then load the project you actually want to work with. I could open that project itself, instead of the program, but it could open the Start-Panel first and then load the project when selected to do so.
I agree that would make the workflow move much faster if it would open to a new scene rather re-load the last worked on one. Bring up a dialog like you do on PR and AE, choose new or recently worked on projects.
