Micropython example for K10 expansion ports

I have installed the latest Micropython release (V0.4.1) on my K10 and everything seems to be working well and I like that you have cleanly added lvgl.   The Micropython examples are helpful but I cannot find any example on using the ports on the expansion chip (P00-P17 on the schematic).  Can you provide documentation and/or examples on using these ports.

Also, I seem to remember on earlier documentation for the Mind+ API, you included the Micropython code along with each piece of Mind+ code.  I thought that was really helpful.  This additional information is not on the latest Mind+ API reference documentation.  Can the python code behind the Mind+ API documentation be added back.
