Improve super and macro key labels

[unional]

The current way of displaying super and macro keys prints super and macro:

They takes up too much of the precious space available, so we have to be creative and cryptic on the names.

Describe the solution you'd like
Use some color hints or a simple s and m (or some icon) at the top right corner to indicate they are super or macro key.

Thank you. We're exploring different ways to do that, kind of like we did with layers.
