Just adding on to this -- the scroll wheel tweak doesn't let you continue adding items to a stack inside the Nether Chest via scrolling once it reaches 64. It doesn't cause a crash (like the right mouse button tweak does), it just stops at 64. Possibly fixable only on the Mouse Tweaks end but I thought I'd mention it here too.

The issue is that Minecraft has three methods for retrieving a max stack size, one on ItemStack, and two on Slot, where one takes an ItemStack while the other one does not and just returns the max stack size of the Container.

For Nether Chested to work properly it's important to use Slot::getMaxStackSize(ItemStack) and none of the others, but all three are unfortunately easily mixed up since in vanilla they pretty much are interchangeable.
