Years and years of Windows and Linux taught me to avoid drag & drop, mostly, except for dragging files around in file managers (and even then, some of the Linux ones…). I learned that it would, too often to be relied upon, do something I didn’t want, cause a program crash (Linux is especially bad about this), put the program in some weird broken state that falls short of crashing, or simply not work.
It took years to un-learn this avoidance of that interaction, after switching to Mac.
Now when I occasionally poke my head into Linux-land again, I don’t have that instinctive avoidance of d&d, and so I try it a lot more. Bugs and bad behavior abound. Anyone wants to see Linux desktop be bad at some things, go hard on drag & drop for a couple days, you’ll see it.
