I would love to see this as well, and it would be nice to be able to create a list of scales and also let users pick their own absolute scale. Also it would be good to display scale ie 1:2,000 above the scale bar, as an option. Last, allow the display to have text with units the developers choose, like 1 inch = 100 feet. This has long been a user question and for now I have to show them how to go to Print, then Advanced, then click 'current' by Scale. Thus it would be helpful if scale was intuitive and discoverable.
