In my frst iteration of OLL! there was only one system. But I have since broken that into three areas. There is OLL! Tools, OLL! Works and soon to be a third area which I will announce here as another project.
OLL! Works is the factory end of OLL! It is where we create the content for the tools. This is quite an involved process and works at all CEFR levels (A1, A2, B1, B2, C1, C2), although we only cater fully for levels A1 through to C1.
I will update this more in the coming days.
