Wish: consecutive numbering in the file name template in the animation controls

Hello David,

It would be nice if you could set the current datetime (preferably with milliseconds) as file name. So you would have a unique identifier to each frame and would be able to use the slider animation also for the creation of random variations of the design in order to explore the design space.

Or is this even somehow already possible with the formatting of the file template?

Another thing that I think already came up a few times here is to add a check box to be able to create slider animations with transparent background when you write .png's

Cheers, Chris
