“Complicated descriptions”? Is there a lamp on one side, or a closet door? Just use that as a frame of reference, I wouldn’t call that a complicated description. Or, if you usually have the same bigs-poon, little-spoon orientation, you can describe which shoulder you’re laying on. But I still think using features of the room is the simplest way. “I’m laying on the closet side.”
Maybe “tinker” is too strong for what I meant to convey, but even switching from Windows 10 to Windows 11 would involve some level of re-learning and tinkering to get things how they like. Unfortunately, they are being forced one way or another, and that’s on Microsoft.
