Glad you like it! Good question about how did I find that variable. It's been over a year and I tried to trace the history of that discovery and I cannot fully recall. This page: https://doc.qt.io/qt-5/qtquickcontrols2-material.html ... mentions the environment variables. I think it had been a lucky coincidence. I had been racking my brain trying to figure out how I would toggle these rectangles without a rebuild, and then I was working with the Material Style feature in QML and I think that when I came across the table on that page labeled "Environment Variables" it just clicked and I realize it could be the answer I was looking for.

Indeed, it's all rectangles, all the way down. (For the most part.)

I implement a lot of QML (with C++ viewModels to back it).

My UI designer actually issued a challenge to me, to see if I could get "Debug Rectangles" to toggle on-and-off without a rebuild. I'm so grateful for that challenge, because once the seed of the idea was planted, my thirst for this "nice-to-have" feature grew until I couldn't NOT solve it.

I now have:

``` DebugRectangle{} ```

... which I place inside any item that needs a highlight. I then leave this code in place (nothing to comment-in/comment-out).

I hijack an environment variable for the toggle. The icing on the cake was seeing that this works both when running a compiled binary executable ("my Qt/QML app binary") and when viewing my QML with just qmlscene. https://github.com/219-design/qt-qml-project-template-with-c...
