I have two little feature requests.
1) Under Edit - Insert Comments should be another option which would allow me to "Insert Class Description".
2) It would be great if I could change the header of the doc block from /* to /** (two asterisks). This for the function description and the new class description.
The classbuilder plugin might help you.
The classbuilder creates whole new files rather than insert into the current file, so ignore the previous comment.
