Just - finally - upgraded to the latest and greatest Orion Core 2018.2 HF6, NNM 12.3, SAM 6.7.0 WPM 2.2.2
I'm getting used to the new Manged Entities View.
I keep switching back and for, I'm happy for that option because I still like the (more compact) display of the the legacy page. Although I do love the added functionality of the new view.
Anyways, can anyone tell me what the Edit Row Properties option in the More drop down is for?

Every time I click it my page open up to the Magic Rubik's cube

and just hangs...... like forever.
Figured before I open a support call I'd see if anyone has run into this.
My Googling, and Thwack searches have been fruitless.
