Maybe it's different between professional and personal projects, but I get that feeling more often as features are not only easier to create, but also come out more polished and consistent.

Doing rewrites to clean up and reorganize has never been easier, so I get to see and feel more of the design space in action. The can be pretty damn frustrating at times, half of which is me/context, the other their nature
