Ideas for redstone pets and other things

So everyone knows that auto farms are great BUT sometimes they don't always work the best because you have to be at the farm to do it like a mud farm you have to place dirt for it and then you have to mine it and then collect it and that takes up a lot of time so i say that the mojang team should add two new things 1. a new redstone block that places a block and as long as it has a piston to move the block that was placed the redstone block can contuie to place 2. a block that can act as a drill per say so it can drop the blocks it drilled AND you guys should add hoppers go up instead of just going down i think it would open so many doors for builds and farms but it would be just perfect and something for the pets cats and dogs there should be more pet types but there should be something you can craft to get your pets to stay in one area while not having to sit because i just feel so bad that my pets can't move around without them following me all the time and more stairs for like dirt and glass and more stuff to make builds more creaitve thank you for reading this may you have a great day or night and just in case i don't see you good morning, after noon and good night
