Distinct buttons for show/hide

I like to toggle (show/hide) the notes, but the shortcut is complex-ish on german keyboard layout and the button takes to clicks to togge. First the button, then ‘hide’ or ‘show’.

I suggest a separate button for each action, one to show notes and a button to hide 'em. This also would make the keyboard shortcut less important.


Note that you can also use the left/right arrow keys to the same effect, holding Alt to toggle all. Doesn’t this work better than UI toggles?
