Hi Alfred, That looks very interesting, and I'd actually like to be able to use it in my applications. Unfortunately I usually use pyramid rather than flask, and this is obviously very flask-specific. I wonder if it could be split into 2 parts. The first would be a framework-agnostic class for tracking and logging queries and so on, and the second would be an adapter that hooks the class into a flask application. It should then be easy to write adapters for other frameworks as needed.
