Feature Request : Modifying or Annotating subtitle

All subtitles are not always perfect transcript. Sometimes, it’s wrong.
So I need to add what they said but not written in subtitle, and to modify some wrong words as to what they really said.
If I can do this, it would help me practice speaking(or reading) very much.


I would love to see this capability.


You could imagine a system where you can import or export sub and as you suggest use the LLN interface to edit the sub.
