Interactions

Toolbar
Toolbar is at the top of the Quick Look window. By default, all toolbar items are disabled until some files or folders are selected.
You can also right-click the toolbar to hide some toolbar items.
Icons View
Icons view displays files in much bigger thumbnails.
You can right-click some file to reveal the action menu. This functionality is the same as the toolbar.
Due to macOS limitation, the extension responds to the right-click action quicker than the click action. Therefore we suggest you to interact with the right-click menu rather than the toolbar.
Path Bar
You can navigate to parent folders with Path Bar if you grant the app “Full Disk Access” in System Settings.

Settings
You can change the settings in the app or in the Quick Look window. They are generally the same, except the “View as List / Icons” setting.

View as List / Icons
When you change this setting in the app, you change the default view.
When you change this setting in the Quick Look window, you change the view for this specfic folder. All other folders will still be displayed in the default view.
