New features

This is first dev release. This release it will work but is missing some features from Casper theme.

Finally a stable release:

Changes since 7.x-1.1:

• Add support for the book module by providing two kinds of new blocks: The Book Navigation (detect if it's on a book page and display the navigation) and the Book Navigation for each book (can be placed on any region regardless if it's on a book page or not). Code cleanup, unifying stuff.
• Add a new feature in the Views Style plugin to let you choose which field will be used to compute the depth (the indentation) of the option text value.
• Code update.
