Allow user to display multiple subtitles at the same time

[vatei]

Summary

Hello, I'd like to ask if it's possible to add support for displaying multiple subtitles at the same time when playing a video.
This feature would be very useful for language learners, or viewers with different languages watching at the same time.
As a basic feature, would be simple toggles, but it would be cool to be able to individually customize sub sync.

Basic Example

Drawbacks

UI/UX to figure out
Added complexity of individual sync (optional but nice to have)

Unresolved questions

No response

Implementation

• I would like to implement this myself!
