CC V3.6.4 added home screen widgets and shortcuts.
The home screen widgets show the last few books that you have read by using CC's launch reader app function: long press on a book or the "Read" action in Book Details. They are automatically updated every time you read a book from CC. If there are no books in your library or if you have never launched a reader app, the widgets will show placeholders such as an empty bookshelf or 'Droid browing books.
There are four widgets:
- A cover list: this widget shows a vertically scrolling list of covers of the last books you have read, with the latest at the top.
- A stack view: this shows the covers of the last books you have read in a stack. Flicking down will reveal the next-oldest cover. Flicking up reveals the next-previous cover.
- A booklist view: this is a scrollable list similar to CC's booklist, showing a thumbnail of the cover, the title, the authors, and the series if there is one.
- A single-row grid: This shows the last few read books (you choose the count) from left to right. It cannot be scrolled.
It is possible that you "accidentally" read a book and it now appears in the widgets when you don't want it to. You can remove a book from the widgets in Book details. Click on the menu icon (the 3 dots) and choose "Remove from home screen widgets." Nothing bad will happen if you remove a book from the widgets that isn't there.
Home screen shortcuts, created in Book Details, will launch a reader on the book that the shortcut represents. There is no notion of "last read"; a shortcut can be created for a book that has never been read. One could use this feature to make shortcuts for reference books, books you intend to read, or books you are currently reading. Once created, a shortcut will remain on the home screen until you delete it.
