It would be super helpful for my team if .SRT subtitle files were supported in Dropbox Replay. Almost all of our projects use subtitles and it's hard to convince my team on Replay without some sort of subtitle/caption support. It's also important for accessibility standards. Lots of reasons to support captions.
As a side note, Replay is great and I love the integration with DaVinci Resolve. You've all done some nice work here Dropbox!
