Ask HN: What do you like to see in a web app quickstarter?

Hi there, I've noticed that when I work on a new idea, creating a MVP or prototype, I tend to spend way to much time on setting up a new project, building out things that are important, but far from urgent to get an idea validated. To save myself time, I created a basic web app starter project (call it a blueprint / bootstrap). See: https://github.com/jelmerdejong/flask-app-blueprint

Currently it sets up a basic Flask project, on PostgreSQL, and is optimised to be deployed to Heroku. Features are: - user registration, including email validation (with Mandrill for transactional email) - basic examples of how to create something in the database, read it and update it. - some basic test coverage

So far I've been adding features / things I like to see myself. But more importantly, to make this useful to a bigger audience: what would you like to see added? Where to you spend time what you rather use to create something unique?
