[Enhancement] Adding an option to disable the double tap on the return button "<" to quit the app.

Hello,

What would you think of adding an option to enabling/desabling the double tap quitting on the app. This button can be used to navigate in the app, without risking quitting it by mistake (which happened many time to me).

The other way of quitting the app would remain, by simply closing the app.
