It used to be the case that clicking and dragging a file with a middle mouse button would pull up a very helpful prompt for when I wanted to do not the default action (the answer to a very old question about Windows-like right-click and drag describes exactly what I'm talking about, with screenshots).
This functionality broke (or vanished?) in Bionic, and apparently never got fixed for Focal. I know I used to use this all the time in multiple versions up through Xenial. I used it back in GNOME 2.x, I know it worked for me when I had to use Unity for a bit, and once MATE was available it worked in that on Trusty and Xenial. I continued to use MATE through Bionic and Focal where it has not been working. If I fire up GNOME (now 3.x, I suppose) in a VM, then I can't get this to work there either.
Does anyone know how to restore this incredibly useful functionality to not need both hands to insist on my intended move/copy/link action over what the computer assumes to be the "correct" one based on source/destination?
