Solder on a small mono OLED, an SSD1306 or SH1106. They are found automatically on the capture chip's I2C bus, so they cost no pins. A round GC9A01 colour LCD works too. Turn it on in Settings and the panel shows a boot logo, then cycles pages: the IP address, the link, what the capture sees, and health with temperature and memory bars.

Pins from the console. Wiring a display means choosing GPIOs, so pin settings became drop-downs of what is actually free, and a new Pins tab shows the whole map: what the board reserves, what you have assigned, and what is left.
