I'd like to suggest an improvement to the workflow while duplicating a page on the sitemap. Currently if you duplicate <filename>, the system creates <filename1>. Then you have to go in and edit the properties of <filename1> to rename it, because how often are you going to keep that name? It would save some time if the system offered the properties dialog as soon as I selected "duplicate".
This may seem minor but can be a non-trivial issue (time spent waiting for the duplication, then having to do one more action to rename) if you're setting up even a medium sized site map.
