For maximum efficiency, keep the key travel at the shortest safe height, around 1.5‑1.8 mm, and use a linear switch with a low profile. That keeps the thumb cluster light and fast. Map your hot‑keys in a 3‑row layout so the most used keys are on the right side of the grid – that reduces lateral motion and keeps the overall shape sleek. For RGB, use a single‑zone, per‑key controller so you can sync the lighting to your stream’s mood without a bulkier PCB. Stick to a monochrome or two‑tone palette; too many colors look like a disco ball, not a professional setup. Finally, test the layout in a video capture to make sure the keys line up with your on‑screen graphics – a mismatch looks sloppy. Good luck, and remember: speed beats flash any day.
