Firstly, my commendations to all the work done on Manjaro, it’s my favourite distro. I’m posting at length to identify the issue more clearly. Secondly, my response now looks like an overreaction since Fabby edited his post. But offence intended or not, this isn’t a case for accessibility software.
The items in bold should not be two separate possibilities! But even so, when I try the last option, press & release, I still get the popup when I drop the file. I am not entirely sure what causes the “surprise move” bug, all I can tell you is I saw it happen a number of times once I was looking for it, but not every time.
In any case, as a computer user of 30 years, I should not have folders with files missing that I did not intend, that I now have to restore from a git backup. (The copies I made have been edited.)
As for the lesser issue of the modifier key not taking effect immediately; this would fine if if the pop up appeared every single time. Still, I should not have to move the mouse to see the result of the modifier key. I should be able to click & drag, hold still, and press the modifier keys on and off and see the little copy or move icon coming and going with each press, like it does in other interfaces.
Yes I much prefer Manjaro’s pop-up! Windows default for “move within drive” and “copy between drives” is a practically invisible decision, and requires you as a user to stop and think, “are these two folders on the same drive, or a different drive?” And it slows you down. As soon as I saw Manjaro’s pop up, I immediately thought - that is SO much better. Now if only it didn’t trigger this “surprise move” bug when I copy with my new-found confidence…
