Another great video, thanks Adam.

I'm eagerly finishing up my current project so I can start working on the K3NG controller/Nextion display project

Hi all

New:
Screen Saver Dim To percentage value is user definable on Config page.
Was previously hard-coded to 5%.
Can now be set 0 - 50%.

Fix: (5.0" only)
Wrong default font for navigation buttons (Clock & Grid) being set for virgin EEPROM. Was font 4, should have been font 5

Fix:
Reference to (previously removed) Toggle Center button removed from Caution Calibration help screen.

Fix:
Screens Saver count up value & screen saver value sides swapped on MoonSat & Sat pages as it should have been!
