The bookmarks can be accessed in a drawer layout by swiping from the right of the screen or tapping the Bookmarks entry in the options menu.
Tapping the top floating action button loads the bookmarks activity, which has advanced options like moving and deleting bookmarks.
From the bookmarks activity, there is an option to load the bookmarks database view. This shows the bookmarks as they exist in the SQLite database. This will mostly be useful for troubleshooting problems with importing and exporting bookmarks once those features are added.
