Return button in topics/library

While working on clubs or reading a book in the library, I've noticed there's no return button. When you're reading a book and you want to return to the library to read another book, you have to click the library location in the top navigation again to get back there. Same for clubs, if you're in a topic in a club, you have to go back to clubs, enter the club, click forum, etc. to return to the club in question.

My suggestion would be adding a 'Return' button in books and possibly topics (can be in all topics and will lead you back to the forum at the location) so it's made just a little easier!
