As explained on this page, I wrote a pretty extensive driver-set for an ESP32 based board with lots of IO, but hardly anyone has that board (fewer than 100 made), so I ported what I could of the code to the WROVER.
Sadly the WROVER lacks a touch screen, so you'll have to wire at least a rotary encoder or a joystick. In the demo above I also wired 2 neopixels and an IR receiver to mirror the hardware on the IoTuz.
