Ditto.

To me, one of the dirtiest words in dev <> designer interaction is "handoff". There's always a point in the lifecycle of any design tool where they start talking about it -- even if they quietly disagree with it in principle. My impression is that it normally happens when they're trying to acquire customers who (unfortunately) practice such dysfunctional team dynamics.

As a developer who designs, I've always found myself jumping between code and visual design tools; but rarely based on the current stage of the project and more often based on what kind of thinking I want to do. If I want to engage with the constraints I more often do it in code, if I want to explore tangents, I open up the design tool.
