First of all, thank you for such a comprehensive and modern project.
I saw this in the CLI docs regarding alignment:
Splitting based on sentences, using a [sentence] placeholder, is currently on the to-do list. Please let me know if you find this feature important, and I'll prioritize it.
My main use case is advanced Anki flashcard creation. I'll be working with subtitles to generate flashcards, and sentence-level splitting is important to ensure each card is self-contained.
In the meantime, I can put together a script to parse the timeline JSON and generate the subtitles that way.
