"Feature" mod element

As of now biome customization is very limited, there aren't that many features you can add to them and some of the ones you can aren't exactly too useful or unique so my idea to change that is a new "feature" mod element, essentially this mod element would work like features do in datapacks and allow you to add them to biomes.

This would also come with a change to the "Features" tab in biome creation to make it more easy to use (right now adding features gets very unwieldy after 3) and also allow to ste a frequency per chunk for the feature

You could allow us to set which biome features generate in inside the feature element so you could add features to vanilla biomes

This would greatly, and i do mean GREATLY enhance world customization as you could add more than just structures (making custom trees would become a lot easier too)

There already is a datapack generator called "misode" that can generate custom features based on your input so you could look at it for some help with implementation

On top of that having access to all vanilla features would be nice
