### 1/5 — Awkward to use

*2022-10-16*

I want to upscale the full image. But here I can only pick a small area and controlling the position of this area is very difficult.

### 1/5 — Doesn’t do anything useful

*2021-08-06*

Only applies to very small image patches, and none of those I tried gave any good results (image is still very blurry)
