Back-button &/or undo to undo inadvertent drag-drop move. &/or add option of a warning before move of a big folder tree.
One of the main reasons folks "loose" items is an inadvertent drag-n-drop or move of items. It might help to have an "undo" or back-button that reverses previous move actions. Or better yet, an option that could be enabled that would ask for confirmation when moving a folder, and/or a folder-tree. (This idea came from a shell extension for windows explorer that intercepts folder moves, and asks for confirmation.) I'm willing to try to contribute this... are there any existing debug/verbose/logging abilities that track each action taken?
