Something interesting I just noticed concerning ctrl+v for pasting a file/folder: it already does exactly that.
- ctrl+v always pastes into the current working directory, independent of selection
- opening the context menu on the cwd background shows “paste one file (ctrl+v)”
- but opening the context menu on a folder just shows “paste one file” without any mention of the short cut
So there already exists a precedent for this behavior and it makes complete sense for “new folder” to do the same.
