Not having this feature has cost me countless hours and aggravation as I use my mouse to try and visually make the rounded corners consistent. It's especially aggravating given that not only do I need to do this if I change the height of the button but I have to make the adjustment across states of the button. I would love to understand why this is not a big priority for Articulate to fix. I understand you don't have much competition out there for rapid authoring tools that don't require JS programming skills. But if that ever does change, I expect the lack of response on some of these basic issues will severely impact it's long term viability.
