River World Generation

Exploration and building are huge pillars of Minecraft that are what makes the game fun, but the current way rivers are generated is hindering to both of these experiences. The way rivers are generated are through biome generation, which means that rivers aren't always rivers but awkward valleys of pastel green. If rivers were to be generated to guarantee water above and at sea level we could use these landmarks to build and explore more freely. Also, with rivers being biomes, that means that we cannot have river caverns that seep into caves. Boats have been improved, and so should the rivers.
