The Slide > Slide Properties dialog is missing impress specific slide-level properties that are accessible from other parts of the UI, so it would be good to also have them in the dialog. I believe a new tab should be added to hold these properties. 1. Slide Name 2. Slide Status (hidden/shown) 3. Slide Layout 4. Master Slide 5. Master Slide Elements 6. Visible Master Background 7. Visible Master Objects
