ORMD 2.1.4.655
When I edit the project settings by right-clicking on the project in the Project Tree and selecting "Edit project", the file types offered upon choosing a Project File destination only include the ".ormdesigner" extension, not the other supported extensions. I can manually set .ormdes2 extension e.g., but it would only be consistent with the "Save As" dialog to have all supported file extensions available here.
