Ideas for ergonomic ways to edit a wiki while gaming

I have to figure out an ergonomic way to edit a wiki while playing a game 🤔. I could make room for my laptop on my main desk somehow. But where to put the other stuff.

Idea 1

A mechanical arm thing attached to the wall behind my desk that can bend and twist. It would have a tray sort of thing on the end that can hold my laptop and be sturdy enough for me to type. I won’t have to move my body to type.

Idea 2

Setup my other monitor to be above my main monitor, maybe with like a wall mount sort of thing. My laptop can go on the side, and it would connect to the top monitor via HDMI. Connect a wireless keyboard and mouse to the laptop and have a tray sort of thing that slides out from under the main monitor and is sturdy enough for me to type. The important thing with the keyboard is that it needs to be further enough behind my main keyboard and be able to slide out to be even with my main keyboard.

Idea 3

Setup my laptop somewhat toward the left, but even level with my main keyboard, and have it facing toward me on an angle so that I can just pivot my chair about 45 degrees to the left and not have to change my posture. <- To be honest, this sounds like the most doable solution and wouldn’t require that I spend any money.
