Water logging blocks: For some reason, the mangrove root is the only block you can waterlog. It would be great to see blocks like leaves, stairs, slabs and signs waterloggable so more farms can be possible.
Trident: It would be great to add a trident with its enchantments as a new weapon and transportation method.
Trapdoor Bug: For whatever reason, trapdoors flip when you place a block next to them.
Trial Chambers?? Since most of the blocks are in the game to create the trial chambers, why not just create it, or maybe a smaller version like with the other big structures.
Drowned: It would be much appreciated to add this zombie variant for better gameplay.
Wardens and Allays: Wardens add a greater challenge and allays allow better item sorters.
Adding leaf litter: With wild flowers already in the game, why not add leaf litter as well?
Add a brightness setting: Caves are annoyingly pitch black, so adding a brightness setting would be much appreciated to make traversing caves easier.
Dripstone functionality: Please make dripstone able to drip lava if lava is above it into cauldrons to create lava farms. Plus make it possible for dripstone to convert dirt into mud if water is above it.
Maybe add more sculk variants?? Adding sculk shriekers, sensors and calibrated sensors could be great.
Offhand items: More offhand items would be very handy.
I understand if you can't implement some of these features but I would be extremely grateful if some of these were implemented, thankyou.
Most of these will probably be added eventually, Dripstone lava generators are already possible.
These things will not be added any time soon as the engine lacks proper support for it:
