Thank you for the nice words - we are happy to hear that you like our controls.
It seems however, that you have not yet heard of what we plan to have in the Q1 version :) Please, review the RadControls for WinForms Q1 2007 beta
Forum and let us know of your thoughts.
As to the NavBar, could you give us some details on the features you would like to see? We are still collecting feedback on this control, which will help us provide a nice version from the very start.
