A bigger desk so I can just roll the chair a few inches to switch to the work laptop.
My original plan was a keyboard/mouse only KVM, probably a Teensy or a RPi or something of the sorts. But I got lazy as the extra desk space has just made it a non-issue for me. I also have a Logitech mouse that can switch between devices, so if I was going to really need that setup I’d probably just get the matching keyboard.
