FOSS gamedev and creative worlds

These are just some things I would like to see in minetest.
Firstly, entity roll and pitch. If it's possible to set the yaw, then I would assume it wouldn't be too hard to add "setroll" and "setpitch"? Would it be possible to allow entities to ignore the light changes for the time of day too? They get darker at night and in caves, but if there was an option to make them ignore lighting changes then they could appear to be glowing. Also, it is possible to check if an inventory contains a certain item so, if there isn't already a way to do so, could a method be added to count the quantity of an item in an inventory?

Thanks, could you give me an example of how to use that?
I thought it would only work for particular stacks in the inventory, not just every one, if they exist.
(and I'll be honest I'm a bit confused about itemstacks)

An itemstack is "one or more of the same item" that fits in a single "slot". The main inventory is a "list" of "Itemstacks" that are possibly empty.

So to count an item in an inventory, the itemstack or stack index has to be known?
