Underground Lushness

So, I know I know we have lush caves and I've done so much topics relating to this. But I ant stress enough, we need more greenery underground! So I've put some ideas together. First off, welcome leaves into lush caves, except for more then half on the time! When a lush cave generates under a forest, leaves will appear in certain areas of the caves. On the top of lush caves, small patches of leaves will generate. These will have some droopy parts, scaling from 2-3 blocks out. They will also generate on parts that go down in a fast motion like they do now. These would be vertical, and go down 4-6 blocks. These leaves control their variants depending what forest is ontop of them. So for example if under a oak forest, oak leaves appear. Now for the shorter bit. Moss will generate on mineshafts logs when they enter lush caves, allowing for moss to go sideways! This would allow so much building potential! This would overall just add much more lushness to caves. Thanks for reading my friend, and have an amazing and fantastical day!
