Curently, when you enable the built in video controller it will auto-hide when the cursor is not over the movie. I'd like to request you make the autohide feature a checkbox option in the Video properties area and have the video controller stay on the screen as the default behavior. Here's why.
When students come to a sheet with an enbedded video, they have no idea it's a video unless they accidentially move the cursor over the video area. It would be great to have the video controller always visible to let users know there is a video on the sheet, and would save developers some time from having to add instructions on the sheet to play the video. I'd like to remove any/all confusion the students might have in using content built by ROME.
