Haptic Touch similar to the one on iOS

Hey guys, just had an interesting idea. Wouldn't it be cool if we were able to have Haptic Touch functionality similar to the one on iOS?

For example, you long press a button, the corresponding menu opens on Touch Bar, you keep your finger on the Touch Bar, then you slide your finger to the desired menu item and when you remove the finger, the button is clicked.

Not sure if I expressed the thought clearly, but what I am talking about is super similar to how it works on iOS. This will be super cool to have!
