The OLED Menu is really useful, especially the Battery% and the Settings is a great recent addition.
The challenge I’m having is that when running the PiTop stand alone using only the mini OLED screen and buttons, you can’t tell how much battery is left. This inspired two thoughts that I’ll put as questions…
Have you thought about adding commands to allow people to add extra menu items that call user written python programs or services?
Alternatively could you allow the Battery% routine to be called from a python program and included in the PT-OLED calls?
The second may be easier for you to achieve, but the first would add great IoT and Robotic flexibility.
