Welcome to TVPaint Community forums !

I think of one more export module. Like the one we have already for HTML (animatic/storyboard) there could be one for the mobiles. An automatic export option.

I have found a very smart GUI done by the NYT. Just to start imagination - If you change sections of the first NYT screenshot to chapters of your film , the second shot could go with a still image (a thumb preview), a headline and a caption for that chapter, the third one could hold the mpeg4 and/or even more text.
Also notice that there are more buttons e.g. for zooming text.

Of course publishing appetizers for mobiles is clever marketing ( large audiences !) - but also is useful for clients e.g. if sent via email.
(And far as I know ToonBoom, AnimeStudio and others don't have it - yet).

I think this is a really useful idea because I've already used TVP's HTML storyboard function with a couple of clients and in each case they were very impressed by it. But clients do like to study (and blow up) individual frames, printout individual dialogs (which is called in the scriptwriting vernacular "character reports" and all professional scriptwriting software have this function) and all these things would be at their playful little fingertips if we had this extension of the HTML feature.
