hello
question 1 and 2: the program is currently not able to save completely everything as you can see it when you hit save and close the application, however, you can access everything needed - just select the component with the most images aligned when you run the application again
question 3: to add more images to a project, use Inputs or Folder in the WORKFLOW tab, and hit Align images in the ALIGNMENT tab to create a new component
question 4: depends on what you mean under “a much higher level for registration”
