Please see this animated screen capture: https://i.vgy.me/zPz8xU.gif
I've just downlaod and installed SoundID Reference for the fist time and this was obvious as soon as I started exploring the GUI. As you can see in the screen capture, some elements of the GUI "twinkle" when the mouse is over them, to let the user know that said element is clickable. However, there are many that don't. At the moment the mouesover behaviour is inconsistent across the GUI. Ideally make all clickable controls visually react on mouseover, for a better UX, otherwise it's difficult for users to intuitively know what can and can't be clicked. Thank you!
