- [ ] improve chrome cast subtitle rendering
    - maybe this will require stamping the subtitles into the video frames manually before submission to the chrome cast (depending on what it supports)
- [ ] add playlist support
    - maybe by allowing multiple file selection? 🤔
- [ ] in the "choose what to play" screen, we should change the youtube button to general streaming
	- we can figure out the stream and how to handle it from the url (i.e. if youtube url, handle as youtube stream; if miruro url, handle accordingly)
