A 'viewer' as with Brushes.
I'm sure this is not at the top of anyone's list, but it is so great to be able to see the process: every mark being made exported as a movie... you have something like it posted on Vimeo - can't we all have one? ;D P.S. Vellum's strength and what keeps it valid amongst some of the bigger boys is it's minimalistic interface and it's simple correlation to this small number of real tools. Literally keep it real & thanks ;)
