It would be a great aid if the model browser was to show the sub-level entitities automatically such that when the mouse pointer is moved over for eg. Revolution1 it opens instantly to reveal the sketch below, and like wise just one click on the sketch would be useful rather than right click and then select the sketch. To be of any value though the dialogue would need to update within say 0.5 seconds as a second or two is a long time to wait.
