Very nice app but with a big problem which makes it unusable for me: upscaled images quality is horrible.

Many other image viewers do a much better job with upscaling, this viewer is very good but not on par with them with this particular task. There is a technical reason for this? Will this be improved in the future?

I found other old complains about upscaling in the other thread with a reply of around 1 year ago but I'd like to know the current status of this issue.

Thanks for your work!
