No. Previously all designs needed to be produced in third party applications because we did not natively support any drag and drop templates. However as of 2.25.13 we've released the first in a series of developments that will transform our app into a fully stand alone platform that doesn't require any third party tools. So as of 2.25.13 you can create a book using our pre-made drag and drop templates. The only reason to use "Book Spec" would be to create a book in a third party program if you feel our program limits you in any capacity. You do not need to download a spec, it's now optional.
Do I need to download a spec?
