Having an option to hide the timestamps on the side of the subtitles

[Oluf775]

I think it would be a good idea if it's not too hard to be able to hide the timestamps next to the subtitles.
The reason is that when I use Yomichan to create Ankicards, the numbers are included, and as there's no obvious way to avoid them with
Yomichan, I have to remove them manually each time.

By the way, thanks for the great app
I really love it !
