I had trouble setting it up. I followed the instructions as best I could and then reached out to the developer with a descriptive inquiry, inclusive of images. No response. Nonetheless, I can't knock the app too much because of my technical limitations. If I could get it to work it would be significantly better than tampermonkey.

I can't believe I was using Tampermonkey for so long as this is clearly better by a longshot.
