The custom.css changes have changed the behaviour of list items, removing the top & bottom margins, so hopefully looking more like a list and less like a group of items spread across the page.

Many of the TTGO Lora32 devices do not have a program button to navigate the displayed pages. It is possible to add a button to the following device:
## TTGO Lora32 V2.1-1.6
Shorting IO12 to ground will progress the screen pages, wake up the device, etc. A simple push switch can be added for this purpose.
