This video https://youtu.be/QRs3QicioGk shows the use of several add-ons very useful: "GoTo" (based on Max implementation), Custom Gauges (Distance to goal, alt, speed) and Custom Widgets (ARM/DISARM, RTL/HOME, WP, etc)
The demo is done using HILs on a M4-V0 for simplicity, but has been largely tested in real flight.
The implementation of GoTo and Custom Widgets needs some extra code lines in the AQ-fw and QGC to work. If someone wants to test, please ask me. Attached the files used for Custom widgets/gauges.
Enjoy
