Hello,
The 34 biomes I discovered don't fit on the screen. After the 23rd biome, I have no idea which biomes I discovered.

Yeah, I need to figure out a better way to handle very long criteria lists

I'm gonna up this. Comming from advancementinfo wich won't update to 1.21 and trying to find a replacement to know what I am missing out.
One solution other than having the tooltip scrollable could be to have missing stuff on top, not ideal but at least you can see a few thing you'd miss.

Also, some other ideas found here:

PS Have to say, your tooltip with colors look 100x better than both other options

The only "solution" I've found for this particular issue is to set the GUI scale lower.
