Ability to MERGE / Unify / Combine subs to play multiple subs concurrently
For multi lingual people/families or as an effective learning tool. Reading / seeing the subs from multiple languages at the same time can be very helpful. There are some online tools that support this but they are manual, 1/1 and cumbersome, being able to do this inline via Bazarr would be incredible
such as https://github.com/bonigarcia/dualsub for functional example
