More default component states (on-click, on-tap, on-mousedown, visited, on-focus)
FINALLY there's a hover state on components! GREAT!
However I quickly ran into a limitation. When the user touches a button or clicks it with the mouse/trackpad, the button needs an "on tap" or "on click" state that very briefly changes a button's appearance to give the visual feedback "your click or touch was detected".
So now that you have HOVER please add ON CLICK/TAP ort whatever you want to cal it.
Basically the component state changes for a definable amount of time before the destination or next state is triggered.
While you're at it, how's about looking at some of the long-time available link states we know from the web, like visited, or on-focus (when users like to use the tab button to move from button to button)
