The main improvement here was around Populate requirements for SD(s) menu command. This wasn't working quite as expected for updating existing diagrams, so I fixed it and filled it out a bit by adding a new dialog. The reqt size is also taken based on the Default size, hence the user can choose a different default size if they want.
