I've found SAAS-like applications (user registrations, emails, forms) aren't where Flask is most useful. Where it really shines is small API's and services. Easy to test, designed to be "little", handle JSON really well. There are also lots of extensions for things like making Redis easier to deal with, as noted in the Kickstarter.
I'd love to see the book incorporate some of those strengths — small, compartmentalized applications — instead of building an app similar to what you'd see in a Rails tutorial.
I'm definitely going to have a chapter on building a REST API. You can see a more complete (not comprehensive or set in stone) list of topics at the bottom of the Kickstarter page: http://www.kickstarter.com/projects/1223051718/practical-fla...
While most of my work is in Django, there are times I use Flask. And... while Flask is simple enough there are times it would be nice to have a go-to reference for common tasks.
(FWIW, advanced Flask-SQLAlchemy topics (relationsips, queries, association tables, alembic etc) and also security issues (what to watch out for with Flask, jinja and WTForms if anything) would be my picks for useful chapters.)
