This is a web link to FamilySearch (familysearch.org), the premier website for genealogical research and family history work.
This app is a simple shortcut to the FamilySearch website, enabling you to pin the app/shortcut to your shelf in Chrome OS or in your App Drawer in Chrome web browser. Enjoy.
Note: the package size is due to using Google's Chrome App Developer, which includes many unused features but allows this app to operate in its own app window.
Update: version 0.2.2 eliminates the requests for useless permissions.
