I feel the same way. When you have a designer who strives for perfection, they seem to think of the edge cases. And when they push you for pixel perfection, it only makes you that much better. Makes me remember how it is not to be "the best" or the one who cares the most in the office

Same here. I usually spend hours going through PSD files and correcting little things like this all the time, and it drives me crazy.
