Suggestion for adding one little tool to Parallels Toolbox (Mac): a show/hide hidden files. The code for that should be minimal. It consists of bundling, within an app, a switch to choose one of the two shell commands: defaults write com.apple.finder AppleShowAllFiles YES killAll Finder defaults write com.apple.finder AppleShowAllFiles NO; killAll Finder There are several available stand-alone apps for showing/hiding hidden files in macOS, several of which have icons that can reside in the Mac menu bar. But why the need for a separate app when just clicking on such a tool in Parallels Tools would suffice?
