Landscape Creation Tool Idea, need feedback

Hey guys,

I’m in uni majoring in Game Technology and for my minor I’m going to create a tool to aid in the creation of landscapes.
The idea behind it is that it’s a tool that automates a lot for you, but gives you the option to tweak things afterwards.

For instance it will automatically slope blend the textures while you are sculpting.
I also want to do automatic foliage generation.

I would like to hear from you guys what you would like automated in the process of creating landscapes.
