Firstly, awesome tool! Have heard of these node based texture generators but never tried them and was amazed at what this can do!
I'm creating textures for a mobile Unity project and one thing I was after was the ability to output a single texture so it will be fast for mobiles (PBR's can be a bit of a drain). Would be great to have this as an export options. For now I wrote a scene in Unity to do it, which has two angle controls on a directional light and its brightness and then it exports an image. Bit fiddly but can take your output and "bake" it down.
The second wish is for support for alpha. Not sure if this is a common thing for such tools but if I want to create a fence or some such then alpha would be really useful.
