This seems like a really interesting concept, the sprites are nice and it seems like the use in-game would be pretty straightforward as well. I am however experiencing an issue with using it correctly.
Why I know it's a deprecated mod (though there are probably also others like it), would it be able to update the UI to support the maximum of 255 qualities?
The mod that I currently also have active is "Infinite Quality Tiers" by notnotmelon. Due to it, the UI kind of breaks down when opening the interfaces for these two objects.
While the scrubber does its work well (though I can't select any qualities over a certain limit), the infuser does not seem to work. Since I can't see the bottom of the interface, I select a quality and press 'e' to hopefully confirm my selection, however, when I throw an item in, use an inserter or a loader, the quality does not seem to increase. (though there are more than enough "quality points").
I can send screenshots or even my save if you're willing. You can add me on Discord with the same username as here.

Huh, I never suspected there was a "Infinite Quality" mod out there, I can easily add compat for that. Just give me some time.

Thank you! This seems to work well now.
I do have one thing but I'll create a new topic for that.
