I used to sit down with a client and change elements of the design right from the developer tools. In theory, it's a nice approach. In practice, it meant that clients started to have unrealistic expectations of 1) how many changes they could ask me to make over time, and 2) how much time it would take to make a change. So nowadays I only do this with designers that I work with, at set times, or with clients that I know I can trust.
