Update 1.21

Hi guys I absolutely love minecraft and I think the thing that minecraft needs most of all is an inventory update. I think you could maybe add 9 different items to all the dimensions in minecraft. 3 in each dimension. And you must collect for all 9 items to create a consumable item. That once consumed adds one inventory slot. You could even make a more difficult one for the hotbar. To extend inventory and hotbar for a set amount. I also think an end update would be very popular. If you could add more bioms and a new structure and new mobs to the end just like with the nether update. Or it would be really great if you could an update where all you do is add stairs, slabes and walls to all existing blocks. That would make building a lot more fun. And also please add more new bloks. It would be great to have a lighter green block with stairs and slabs than dark prismarine. But please not a another Cyan color. There's no pure green or blue blocks with stairs and slabs.
