I create a lot of animated display advertisements in Hype. For every job, a requirement is that static versions be supplied as jpg or gif. Adobe Edge animate used to have a 'create poster' function and would export a frame from where ever your playhead was placed on the timeline. Generally it's the last frame you want to capture. I've been taking screenshots, but it's quite fiddly. A camera button or advanced export option would be wonderful.
I know this has been on your 'to do' list for a long time. What's the status on this feature?
