Hi Brian,

re:
> Is it possible to make the edit frame more visible, and/or with larger icons, for UHD monitor?

Yes, you can do it by modifying these PNG bitmap image files, resize them to be larger in an image processing program:

GripFrameCorner.png
GripFrameCorner_highlighted.png
GripRotation.png
GripRotation_highlighted.png
FrameOrigin.png
FrameOrigin_highlighted.png

You can find those in the UI folder in the MoI install and you can replace them there or also if you make a UI theme you can put the resized ones in the theme folder and they will get loaded from there.
