The Journal is a view that stores your Journal notes, highlights, verse notes, saved verses, and folders in one place. It can be accessed from several places: tapping the circular square pencil icon in the Bible tab (Quick Flip icon), the Recent tab in the Bible tab's library, or from the Bible tab's Quick Access menu (blue circular square icon).

You can search for keywords in your notes, verse notes, saved verses, and folders using the top search bar in the Journal view. Created folders are listed in the bottom half of the main Journal view. 

Tap the Recent category to view all recently edited content. This can be a helpful place to locate notes accidentally moved to a different folder. 

When you're inside of a category, such as Recent, and want to return to the main Journal view again, tap Journal on the upper left:
