Hi @chubbybutton -
Glad that you got it working! My coworker reminded me that we added the information to a guide, so the surftrack fixit route is not necessarily required 
Can you share a screenshot of the Bridge UDP9090 you’re referring to? If this is under the Ping sonar devices, that is normal.
Alt_hold actually uses the pressure sensor to hold depth - this will move up and down with the waves though!
SurfTrack is the new flight mode that holds a fixed distance from the bottom based on the Ping returns. You’ll see updates to the setpoint when in that mode and adjusting your depth via the right joystick. It is a new feature only in use by some customers so share feedback on your results using it!
The surftrack extension is telling you that you may want to increase the RNGFND_MAX distance to 50m, rather than 7m, so that you can follow the bottom over a wider range of… ranges.
I’ve not had trouble dragging widgets to the top bar - it can be a bit tricky as they need to land in an already open area on the bar.
