Is there a key control (Shift, CTRL, Alt) that can be used so when drawing a Ellipses or Rectangle so it will force symmetry? My users are complaining it's tedious to draw perfect circles or squares, as they have to draw them, and then toggle on the symmetry from the properties menu. Most drawing applications allow you to use the shift, ctrl or alt to force symmetry while doing the actual drawing.
Thank you for the suggestion. We will add ability to build symmetrical annotations visually in next version of library which will be available this week.
