1.21 mod features (suggestions needed :3)

[Zedroid]

So im making (probably a really scuffed) 1.21.1 mod for skyblock... I cant guarantee that it gets constant updates, nor can i guarantee that it will be bug free...

BUT I think the gui of the mods for 1.21 that are out rn are pretty gross in both feel and looks, and a lot of the stuff doesnt really do what I want it to do.

so for all 1.8.9 players who are moving to 1.21, what features do yall think i should add
