This is the concept we are getting VFB to look like.
Buttons are in their idle state. They are not supposed to look like Win 95 beveled buttons, but at the same height as surface around, with some sort of space around them.
When you hover over them, the space around them turns blue to imply as if there were blue LEDs under the button and glowing through that space around it. Although it's just a line, not full glow effect, to not look too fancy.
