Feature request: Improve transcript editing and TXT export

I imagine it wouldn't take this long for some of these features, and I may consider helping with this, but I need it to where it correctly separates every speaker segment away from each other after it gets exported. Currently, after adding speakers and merging segments, it will export multiple speakers into the same segment in the txt file.

Ideally, it should look like this:

Speaker 0: my segment here Speaker 1: my segment here

No extra newline in between each segment, unless you add an option to do that during export. I want this to be like how ElevenLabs exports transcripts, except they add newlines between segments and they add [] around every speaker label ([Speaker 0]).

Lastly, the transcript editing feature should be similar to ElevenLabs where speaker labels should have their own column and also be editable. After swapping or editing the speaker label, it should update in all other places in the transcript. There should also be a way for us to add new speakers like in ElevenLabs, and to also merge all segments from one speaker to another.

If you want examples from ElevenLabs STT, let me know. Also, if you need help with this, can you point me to the relevant files?
