Default containers like chests and other mod containers allow for the sorting and easy extracting/filtered insertion of items, but Personal Chest GUIs don't seem to have this functionality (from Mekanism).

Steps to reproduce
Open Personal Chest with Quark installed

1.19.2 Forge

this stems from us only supporting normal blocks & iirc mekanisms chest doesnt extend the normal chest classes, however ill take a look anyway and see if theres anything i can do about it

Got it; thanks for taking a look regardless

For reference their chest block seems to be extending BlockPersonalStorage, a custom class they made
