I think keybindings is the most crucial topic to make the beginner comfortable, the default ones are crap. Reducing the stuff to the most necessary fast-to-press keys is essential! Comparing to Digital Integration's "Tornado" everything is a lot more complicated, for example gear up and gear down now is a process which can be executed with engine normally or without engine required to be done manually like in the no-fuel-tutorial-emergency-landing (2 different keys for up and down = 4 keys). Same with many throttle options. Another thing is radio frequency: if you don't hit the right one there is much silence! (Digging into the files eventually will result in finding them).
Stalling is different and will not be prevented automatically by assisting systems. It's harder to put the nose down back into airstream, when falling like a rock. Gear down command helps with that (Just figure which one)
Comming back to no fuel situations or other emergencies: if weight reduction is required, this command needs to be keybound as well (jettison cargo).
