Is it still true that there is not a way to remove or edit slide comments? An old posting in Feb 2007 below mentioned this fact.
Can you add a feature to allow editing and removing comments in a slide? Same would also be useful for "notes".
I am using "SlideComments" to markup a template so my code can easily decide what type of slide and how to edit it. However, I need to remove the comments from the end result; otherwise, the comments always get printed when you print the presentation.
