Similar to how collections work, it would be nice if there was a way to timestamp scenes from movies or shows and put them into an almost gapless playback collection. Instead of manually playing 7 different movies with cool fight scenes in them and fast forwarding until I found the scene I wanted, I could bookmark those scenes into a scene collection titled “Best Fight Scenes” and just play that. This could also be super useful for concerts, surround sound demos, best episodes from a TV series, etc.
Oh! I know they don’t answer your question - and besides, they’re both outstanding feature requests themselves. Just wanted to share those with you because they have some common elements and would require some common underlying technology.
