My list is 3- maybe 4? things, but I added all the detail that I could
In my opinion, Minecraft needs a better way of using redstone, something to make it more compact and much less out of view, that would allow players to build structures designed to look good, but can also hold cool contraptions and stuff such as an elevator n a big mall, realistically, they aren't too wide as the electrics work from above, I'm not saying I want ropes and things that can pull up a ton of weight, but small and more slick redstone to go to the pistons so that it doesn't stick out for miles on end, even if it is more complicated to use. and also, some way of counting, like a stop watch, and making it reset-able and on selected seconds, something becomes activated other than that, lag isn't too big of an issue for me now I use a better computer than my old netbook, Mobs need to be smarter, especially wolves, which stay permanently mental at players who you accidentally hit (or vice-verse) and A whole new dimension, I know it's a pretty big thing, but A vanilla dimension filled with all sorts of new blocks and dungeons and other things to explore would bring back the excitement of Minecraft back to me, so far the most exciting thing I find is command blocks, and they're technically not part of vanilla Minecraft yet, as you have to use cheats and commands to get them, anyway, i know it's a looooooooooooong list, but yeah, these would be amazing things to see in Minecraft, in my own opinion
