We do lots of security at the UI and database level. Tracking down an issue with a view and Read_Only_State of the DDO supposedly set, but it was still allowing saves. Lot's of debugging to find the issue. And had the idea that being able to show if a DDO is set Read_Only in the dd_debug would be nice. We use our own custom version of this handy dialog, so I added checkbox to show it.

I'm thinking this would be a nice addition to the std. dd_debug.dg
