Place the "Next Poll" "Previous Poll" buttons at the bottom of the full screen view
It’s a great idea; however, I’m marking this as declined and here’s why:
Each poll is an individual Flash object that you load from the site. The Flash controls (including full-screen button) interact with this singular poll object. So, if you clicked the “next poll/previous poll” button a new Flash object would still need to load before enabling you to go full screen.
Now could we build a Flash application that allowed you to cycle through polls without the web interface? Sure. But we already offer this functionality in the form of embedding polls into a PowerPoint presentation.
Another reason we haven’t invested the time into a “poll presenter application” is we’d like to do away with Flash charts altogether. We plan to move to Html 5 charts in the future, and I imagine your suggestion will be implemented in that release, as it will be much simpler to accomplish.
