I'd like to ask if it's possible to add a skip to waypoint feature so people don't need to stand in front of the computer for 12h in a long trip. (Like the ToLiss a340)

You don't have to stand in front of the computer for 12 hours, the plane has a function to speed up time up to 4 times

For the time being I recommend this tool:

Works perfect with inibuilds aircraft.

However 4x is too slow for long haul, the pmdg 777 supports 16x, now that's really good for a long hauler. I'm a family man, 4x doesn't solve the problem, for me, skip to waypoint is the easiest solution.
