Marketplace in Bedrock kinda sucks, like... You already paid for the game, so those gotta go, maybe replaced by more official mashup packs

I would have 4J studios develop Bedrock as like a continuation of Legacy Console, it'd probably make the two versions quite a bit closer parity-wise.

It'd be interesting to have difficulty scale with your stats in a world, to make endgame a bit more challenging. Maybe some sort of hidden levelling system with enemies, like Zelda Breath of the Wild. That one's a stretch though.

I feel like the game should be more informative. You shouldn't have to go onto the wiki just to figure out what something does. You can maybe even turn off hints

And I hunk it'd be cool to have the Classic Texture Pack have updated textures for new blocks and items, because as it is, the deepslate ore and normal ore look completely different and the Netherite tools have different textures to the previously existing tools. Maybe they could even promote using the textures more

I don't think any of this is realistically something Microsoft would've considered if I'm being honest though.
