When I am editing a flange in the Bend Edit dialog box, and using the offset option there are two side of the flange that can be offset: OffSet1 & OffSet2. There is no visual indicator which side of the flange is OffSet1 or OffSet2 so I am left guessing. I recommend that a color be assigned to each side and a the side of the flange effected be highlighted in that color. For example OffSet1 is red and the side affected by OffSet1 be highlighted in transparent red. Same for OffSet2 but with blue.
