THEMA:

I would like to be able to set up the Jetibox emulation to display text-telemetry for a model to immediatly jump to the top of the MX menu tree to display the values without any additonal navigation. This should be configurable like: Default (as we are used to now), TX, RX, MX menu.

There are two reasons for this:
First, old non-EX sensors don't transmit EX data at all. By defining the MX menu as start position for the JetiBox emulation, it would be very convenient for the user, because he immediatly sees the data of the sensor.
Second, if a complex sensor wants to display plain text status information, it can't use the EX protocol, because it's not designed to transmit single values. Only numbers can be transported - or the 32 byte text frame displayed in the Jetibox emulation. Again the user needs to press 3 buttons to navigate, before he has access to the information.

Example:
I am surveilling the start procedure of my turbines and display the different start phases as a text message like "pre heating", "spooling up" until it finally reaches "operational" , so I know I can lift off the helicopter safely. After the flight, I display the shut off condition "RC controlled" or in case of a failer "Out of fuel" (happened twice already ) ... followed by "Cooling down" until it is ready to be "Shut Off".

Note taken. Quite reasonable idea.
