One thing I would really like to see in a future version is the ability to render only a selectable part of the scribe you are working on (maybe the same way you can select multiples assets on the timeline).
With scribes that are more then 3 or 4 minutes in total, it takes a lot of time to 'test-render' to see if all goes okay.
Being able to select only a part of the scribe to render, would speed up production time in creating a VS animation.
It is also a big time-saver if you only have tweaked a small part of an existing VS: render that part, and insert (or overlay) it via a post-production tool in the original movie.
I have asked for this too. Hope version 2.2 comes with it.
