It would be cool if we could control playback on anything we play in the private theaters. This would give people an incentive to use private theaters. Right now I usually just take a free public theater so i'm able to earn credits, credits I barely use. This would encourage people to use private theaters and give them a use for their credits. It would allow people to pause a movie they're playing to grab a drink or something similar. It would be very useful for skipping the OP or skipping the ED to see some end-scenes. It's quite repetitive after a while. The list goes on, you get the point. It seems like something worth trying to develop in my opinion.
