Awesome, that STMPagination script looks like exactly what I need. Thanks a ton, man.
And thanks for giving a look to ellipsis mode. It was a thing I didn't think I'd ever need until I ran into the cruel realities of pixel art and integer scaling and sometimes you just need to make sure things are going to cut off in an elegant way. Haha.
Thanks again! I'm off to rip some TMPro fields out of my UI once and for all.
