dimension requests

I have (3) requests I'd like to see in Bricscadsometime in the future.1. When updating dimensions to reflect a change in the dimscale, have the leaders update also.2. When clicking on a linear dimension there are (2) grips that show up: one on the end and one in the middle. It would be nice if there could be a grip on each end for the sake of being more user friendly.3. Make stacked fractions easier on the eyes. (make larger?)Minor stuff but hey - can't hurt to ask!
