I would definitely be interested in an update to caves, abandoned mineshafts, and even more added to exploration. I really love mining, but spending that much time underground seeing most of the same things I saw years ago can get kind of old. I'd also like to see some more above-ground buildings, biomes, or objects to help make world exploration more rewarding and fun. They definitely made it more fun recently what with the new structures and maps you can find, but even more in the future would be amazing!
