So I'm new to custom mechanical keyboards, but I've enjoyed mechanicals for years.

With the addition of two Drop Max keyboards (one for home, one for work), I've been really enjoying the customization of my keyboards. But then I started wondering: what do I do with this extra USB-C port?

It only took plugging in a USB-C flash drive to confirm it has USB pass-through, so of course my first thought is "What sort of peripherals/accessories are out there that would work with this port?"

I'm sure there are probably displays, buttons, knobs, etc, but what have you found, considered, or even actively use? Please feel free to share thoughts, links to items, and/or pictures if you have an awesome setup! I'd love to see how you all put that extra USB-C port to use.
