@gerasimos this is a fantastic idea. I like the idea of customizable long press features for each button. I do like quick access to settings with the middle button, but maybe some additional features could be long press the top/bottom buttons for backlight, screenlock, stopwatch/timer, alarm, start last performed activity (ie. run,swim,bike)[useful for those of us who have one predominant activity]…just to name a few. I am sure that there are many others that people could think of.
