The App Info dialog is now enabled by default in the last chromium build. It means users can see basic information for their apps directly from the App Launcher and don't have to go to chrome://extensions anymore.

The summary tab contains what you expect:
- App name,
- App description
- App version
- Link to the Chrome Web Store
- "Create shortcuts" action
- "Open as" action if the app is an Hosted App.

Where as the permissions tab has:
- Required permissions
- Optional permissions (https://developer.chrome.com/apps/permissions)
