There isn't either any sort of alert. On MacOS the trackpad can easily select a whole directory and move it some place else without having any alert or possibility to undo that change

Would love to see this. When explorer panel is focused, you should be able to undo/redo folder/file operations. This feature request would go nicely with #26339 / #43555 / #52844.

WebStorm handles these features nicely (if inspiration/examples are needed).

Having these features would also make it easier to justify disabling the confirm popup settings (e.g. explorer.confirmDelete and explorer.confirmDragAndDrop.

I have puhsed a change to tackle this. You can try it out in VS code insiders from tomorrow and let us know how it works for you. Thanks for the feedback!
