Improvements to new group sharing (Dec 2019 update)

[RobBlash]

The new sharing process is nice, but it's not very user friendly for someone who owns and manages a lot of groups. See screen shots, I would like to see these things improved. Particularly, a way to quickly see a list of groups an item is shared with. Showing the icons is not helpful to anyone who maintains many groups (I maintain 38, I'm sure many people have more).

I'm no fan either, specifically of them using Group thumbnails for the icons. What a fantastic and efficient way to quickly decimate the design language that Esri's Calcite Team has worked so hard on developing and evolving for the last several years.
