Under X11, if I drag files on the same filesystem, it automatically moves them, and if I drag them between filesystems, it copies them. But under Wayland, it always copies the files, even on the same filesystem. This makes moving files much harder than it should be.

One of the other side effects is that if you select 20 files and then unintentionally drag them a bit and immediately release, you end up with 40 files in the directory, half of them have "(copy)" inside their name.
