The explorer.exe / open / xdg-open switch for opening a folder, revealing a file, or opening a file with its default app was copied across eight commands (export, save, PDB, diagram, package extraction, CFG diagram). Replace those copies with one ShellHelper exposing OpenFolder, RevealFile and OpenWithDefaultApplication, and route every site through it.
