@Johannes11833 What's the black version and python target syntax? Latest black on python 3.11 doesn't show any changes

I don't understand, how your changes would allow for easy interruption. Even with the popen handle being returned in the copy function (which it is not atm) for example, the rclone copy operation is first fully executed before we receive the handle.
So an interruption would still not be possible with you changes the way I see it.
Am i missing something?

The flag allows for a return before the wait. I ofc forgot to return the handle everywhere 🤦🏾‍♂️
