I actually didn't do anything fancy with displays, just what layer I'm currently on, but I am using the keeb in a way that I almost never even look at them. They do tell me if the keyboard is stuck (happens because of my soldering skill issue). The displays are very, very cheap, so it's hard to regret buying them.

I actually designed my keyboard's PCB myself (very easy, just steal things from other keebs and follow manufacturer's constraints), so I won't show it here, but it's so cool, and it fits in the box in which the components were shipped in so I don't need to buy one lol
Keycaps are default Kailh, they are flat and allow Choc spacing, it is possible to glide the finger over the keys (haven't come up with cool ideas on how to use this tho), and switches are 25g., which really is bliss that I recommend to everyone
