i suggest for end user comfort improve *New Report* to handle also Forms.
1. user open document (e.g. sales order)
2. print form to pdf
3. selects ** New Report **, system creates a simple tabular report instead of original form copy. IMHO - we can easily re-use copy print format (available under printformat>>copy/create feature.). This working properly. As result user able to create form copy easily.
