Many applications which support images or shapes allow resizing them in relative terms, i.e. using percentage values. But - LO Impress/Draw doesn't - and it should. So, I propose users be able to select how sizes are displayed in the Position & Size dialog, so as to be able to set them using percentages, with the options: 1. Absolute size 2. Percentage of original size 3. Percentage of current size 4. Percentage of page / slide size in corresponding axis Option (2.) is the most important, options (3.) and (4.) are useful in my opinion.
