Hi! Thank you so much for your feedback! :)
Autoleveling is supposed to be activated when moving the stick up/down, not pressing it if I remember correctly.
About the honking: I used multiple buttons for some functions, because I thought that everyone should be able to reach the function with the button most convenient for them.
It should not be much of a problem to add an option to select which button should honk.
I will try to upload a new version soon.
