I'm curious as to how necessary this is given the live visual tree helpers built into Visual Studio that show you the layout bounds of every element in the app, not just in a grid

[michael-hawker]

@JohnnyWestlake the helpers only let you see the adorners for one element at a time, and that won't always be aligned with the actual layout of the grid (i.e. the item being centered in the grid and not filling up the space).

So, if you're trying to debug the grid layout and frame itself, it can be a bit tricky to understand what's happening with just the adorners for an element within the grid.

This request has been added to the WinUI Library's Make Grid Better feature proposal so going to close it out here for now. If they end up not taking it, we can re-open and investigate in the future. Thanks!
