why are these things not in minecraft

1. Tinted glass panes can't be made simply because of the way tinted glass itself is created
2. Nether brick fence gates wouldn't make sense: A gate made of solid brick would be very ineffective
3. We don't need lava-proof boats, we already have Striders
4: The Double Ender Chest wouldn't work, because you'd be cut off from half of your dimensional inventory if you opened a normal Ender Chest
And 5, for those in the comments: Minecraft will never add Vertical Slabs. Get over it.

Me joining Mojang and secretly adding vertical slabs

but WHY wouldn't they add vertical slabs?

Because it would mess up the physics.
For example, you would be able to make certain blocks that normally cannot face sideways face sideways by making them out of slabs. And which half of the block would be considered the 'bottom' in terms of vertical slabs?

Yeah I don’t want vertical slabs!

fair point, but i feel like this could be partially resolved by making it so that vertical slabs cannot connect to form full blocks, or at least making it so that slabs of blocks that look the same on all sides (like stone or smth) CAN do that, but when they do that it automatically reorients itself into the top-bottom position to prevent MC's physics engine breaking? i'm no coder though, so i have no idea if this can be pulled off or not

I want to be able to make stairs and slabs out of concrete and terracotta

Double ender chests is a no cause what would happen if you fill a double ender chest and then open a single one

maybe the last 27 slots just wouldn't show

I agree with everything expect double ender chests

where did the same for Minecraft?

I NEED GUNS

that makes sense

when vertical slabs

tinted glass panes exist

double ender chest is the only one I think doesn't really work, vertical slabs are better
