The feature

I’d like to propose adding blurred side borders in the slideshow for images that don’t fit the whole screen and leave empty black space.

I’m aware that not everyone likes this effect, so it should be optional and enabled or disabled in settings.

Here is an example - with and without blurred borders:

![blur2](

![blur1](
