Bedrock environment features in Java

While I prefer Java edition to Bedrock, there are some things I'd like to see in Java. Firstly, the generation of trees with vines or of fallen trees would add so much to the games environments and I would love to see these in Java. I also would like it if Java leaves changed color when it was snowing like they do in Bedrock. It's just so pretty and would add so much to the games snowy biomes.
