Added: Reveal save location action, plus an optional reveal() method for custom handlers
Added: SaveRelativePath expression: the path from the selected folder down
Added: On reveal error trigger
Changed: ACEs are split into Save Manager, Errors and File system categories
Changed: SavePath now returns the full path on Node.js and Pipelab. On Webview it returns a platform path using an environment token, since the real path cannot be read there
Changed: With Auto load off, the default data is now loaded into the JSON object at startup instead of leaving it untouched
Fixed: SavePath was missing the root folder on the Node.js backend
