Maximize and Minimize handles on Editor windows

This is on 8.1.2.

The UDT Definition Editor doesn’t have have handles to maximize and minimize the size of the window. But the Gateway Event Editor does. Is there a reason for this? Can they be added?

I also noticed that the SQL Query Builder window doesn’t have them either.

Having a these handles makes for a better editing experience as I don’t have to keep dragging the sides of a window in order to peer into the details.
