I remember asking about something like this a few years ago and I just want to say that it looks awesome!

I implemented it 
with a big help from Arjen. Took quite a bit of effort.
Glad you like it.
I wanted this as well, if not for anything else to better test copying/transfert speed.
This was a long asked for feature indeed.
This isn’t perfect yet though in all cases, it should be improved over time.
