Disappearing biomes

The game is starting to get a little too complex and I am wanting more simple updates such as new seeds or farm animals. It would be pretty great if we could have an optional tutorial for specific items because in the 7 years of playing I still cannot figure out redstone or command blocks and have been putting off learning since I am not a daily player. Villages are still pretty buggy as well with their spawning areas. Haven’t seen many in the snowy biomes lately and would love a jungle village. Also some more focus on the desert/mesa and I have still yet to have found a mooshroom island in the 7 years I have been playing. Swamps are also very rare now and those could be pretty cool with more mobs. It would be fun to get to see some more of these older biomes a bit more Kind of random, but a quick mob idea would be bears or otters.
