several suggestions

Hello, here are my suggestions.
First of all I think there are missing blocks to make the worlds more realistic.
These are some Blocks Spheres, Cylinders and half hollow Cylinders, for when
the water has the possibility to flow use it as water pipes, Cone and
cone trunk all this programmable blocks.
Another suggestion would be to have the Texture and Blueprint package in the
folder of each world and automatically detect it, in this way each world
would have the textures and objects in place without interfering in others.
In the part of the land, to have the possibility of turning the textures
so that it does not look so linear, the leveling of the land rises a
block at the moment, the ideal would be a quarter of block besides the
possibility of inclination to be able to obtain perfect ramps.
I do not know if it happened to me, but I've seen other similar games and have these options.

I already have it done with tables with texture of the terrain, but it does not convince me, this way I can not mix textures to give more realism
