Would be great if we can do these small minor UI improvements:
Increase the hight of the Position and Audio buttons to at least height: 100px; (or maybe fill all the way, like board 80% buttons 20% of screen).
Active/focus states. When i click a button sometimes it stays active until i click the other button or somewhere else on the screen.
Show Feedback on Error and Success: Instead of changing text color to green/red can we change the background of the button instead? The text change is barley visible for me.
