I'm not sure if this is possible with the current API and I imagine it being a considerable amount of work but it would be very cool if anyone could write a plugin that lets you tweak some options for terrain generation. Basically I want to set the sizes of biomes and the ratio ocean / landmasses. This idea came to my mind because the default vanilla terrain generation looks a little strange if you sight it from distance. There are many tiny desserts being just a few hundred meters away from rain forest on one side and tundra on the other (and that next to the see ) It is very hard to find a place where you can build a city that is placed in only one biome. While thinking about that another idea came to my mind: Having big continents positioned in one big _connected_ ocean. Considering that, I believe that many people would like to customize some of their worlds; having one world with many mountains and a rather flat one, or one with large flat spots for building followed by big cliffy mountainous areas to be explored. Just to give some examples. I believe this Idea has much potential but I don't know if it is actually possible and if it is I am not the right one for that task. So, hands up, brave developers!
