Custom Loading Screen...But More Complicated

I saw there was another suggestion along these lines in the issues, but I had a bit of a different take on it. I'm not exactly sure how the mod works or anything, but say there was a folder where you put in backgrounds. Plural. Then, whenever the loading screen pops up, it randomly chooses one out of the possible options. Perhaps you could also rotate through the list, as an alternative. Or maybe random with no repeats until you've chosen each at least once, whereupon you clear the list of chosen backgrounds and start over with the randomness again. As another alternative, maybe you could remember the last N backgrounds you've chosen, and choose the next from the other backgrounds. Anyway, you can see my idea, right? Basically, it's not just being able to choose a custom background, but actually being able to set a bunch of random backgrounds, as well as adding some configuration options to the mod. The only real problem I see with this is aspect ratio and image size, but I imagine you could either stretch the image or simply require a specific size.

Another possible solution to the aspect ratio and image size problem would be to just fill in the rest with a solid color, possibly configurable. I imagine that may work, too? Either way, this mod is already a must-have Modrinth mod :)
