P: Don't auto-show filmstrip

I want to call this a bug, but I think it's actually a feature I hate. I often use Opt-C to show two images side-by-side. When I do, the Filmstrip appears at the bottom without my asking it to, and persists as I continue to work, until I tap "/" to turn it off. This drives me nuts! There is a time and a place for Filmstrip, but I'll ask for it when I need it. There is no use case I can think of for auto-showing Filmstrip in Compare view and I'm tired of turning it off all the time. 

Please make Auto-show Filmstrip an option we can turn off.
