> if Apple would make a dock that I could plug into and have my apps move back into the position they were in (including correct monitor) when I unplugged the cable.

Isn't that handled by software? That Apple hasn't been able to provide for ages despite originally bosting to have the best monitor support, and now releasing "the best" external display with Studio Display?

Yup. It's been a pain for me since forever.
