Feature description

it would be really useful to display the ratio of likes/dislikes.

(the app of the picture is Show YouTube Dislikes)

Why do you want this feature?

having a ratio of likes/dislikes makes it so much easier to spot a good video from a bad one.

Why ist the feature relevant to this fork?

this is the only fork of NewPipe that displays YT dislikes.

Additional information

I posted the same suggestion in the old repository.

perhaps it could be an optional setting, in case that not everyone wants it by default.

(I just made that up in Photoshop)

btw.... I think it would be better if the ratio had two more digits after the dot .

e.g. 4.29 / 5

it looks more precise.

hey, thanks for implementing it.

but... perhaps it would be better if the percentage was displayed for both the likes and the dislikes? (and not just the dislikes)

here's a comparison:

1 - original	2 - alternative	3 - alternative

(those stats are from this video)

I think the 3rd one looks really good... what do you think?
