You are correct that we currently don't have any plans to create a WPF time tracking app, but it is a very interesting idea. We are in the planning stages for 2011 R2 and are thinking about ways to improve the time tracking abilities in TeamPulse. Having a small desktop app to help developers keep track of their tasks could be a very useful feature.
Thanks for the feedback, it is always appreciated. I've given you a few Telerik points for your time.
