Field in Object links to another object in the same 'table' - How to do a lookup?

Lost a reply somewhere along the way.

Thanks Matt and JD. My sanity is restored. I could have sworn I added fields to the popup without the “search fields” when we were experimenting with Skuid a year or two ago.

Is it possible to change the pop-up title?  Saying “Select M2Setting ID” isn’t the most descriptive. (It’s the object name)
