Yeah it would be very nice I am going through and making Custom Strataframe Themes to match the Dev Ex themes. Right now I'm kinda guessing as to what to change but it's coming along faster than I thought it would

Yeah, at some point we will have a visual designer to allow you to create themes.  But if this is the only thing you want to change, you already have the ability to create custom themes.  Just copy over the BlueSkies Theme (or whichever theme you want to use) and set the GroupCornerStyle property to your liking then load that theme instead of the other.  Another option is to set the ThemedGroupBox ThemeSupport property to ColorsOnly and then you can control the corner.  But the visual editor is coming....I have wanted it recently myself

In the last class you  mentioned something about adding a theme designer to a future release of SF so this request may end up being irrelevant. I'd like to be able to set the corner type in the DefaultApplicationTheme control for themed group boxes.
