Thank you so much!
I did actually want to add tooltips in that way, instead of just on the buttons. One of the reasons I didn't is because I saw no easy way to customize the appearance of the built-in tooltips (without some method like using some roundabout method like a plugin). Maybe I am missing something though? I know there is a mehtod called _make_custom_tooltip() but I was intimidated by the though of overriding it haha.
In any case, thank you for the feedback and thanks for playing!
