NW Properties Viewer gives you a tree view of your property groups, allowing you to expand or collapse that property. The property values are shown in bold so you can easily see their values. When right-clicking on a value, you have the options of:

1. Copying that value to the clipboard,
2. Finding and Selecting ALL objects that match that property (Not available in this Trial version),
3. Isolating ALL objects that match that property (Not available in this Trial version).

Note: This app uses a custom installer (and not the standard App Store installer).
