Adding Parent and Child post can help organize and separate ideas without having to explain everything in one giant post. For example, let's say I suggest a new biome. The parent post would talk about the appearance and simple structures. It would also introduce new mobs and items that are briefly explained. The Child posts will each individually talk more in depth about the more complicated features like those mobs and items. Adding a way to link your own posts together could also help post that on the surface need more context. I have found time and time again that people will post about features related to another post that on its own makes no sense.
