Suggestion: "Watch later option!"

I have been a fan of FB for many many years, and love the work you guys do to keep the site free/affordable! I also love some of the new additions, and I wanted to make a suggestion-- instead of just having an option for "add to favorites" and "add to calendar" how about an "add to watch later" list? Sometimes I see a workout I think I would really like and don't know when I'm going to do it yet, so I don't end up putting it on my calendar. It would be nice to have a third option!
