Suggestion : Scrap film option
Ever have all very long film shoot options when you don't want to do a long one but are too low on diamonds for re-roll?. In a studio with film trophies, you can always let it expire without suffering exposure loss if you are already going to have enough, but that still leaves the issue of waiting it out and then having to wait the next hour for the next one. So, some button that just kills it dead right now and starts the countdown to any remaining shoots in your day. I guess whether or not it depletes your possible daily total would be a subject of further discussion.
I know, I know. 1st world probs but I have this going on right now and have 3 more to do after this one. I wish I could just trash the shoot and get the timer going toward the next
