D-Spy was getting pretty long in the tooth using so much infrastructure in GTK that has been deprecated. Particularly GtkTreeView. Makes sense given that it was originally a GTK 3 application.
Now that we have libadwaita and lots of easy GtkListView data binding, I took the liberty to revamp it. I’m sure it could use design review and lots of paper-cut fixes. But that is why we land this stuff early in the cycle.
Now that people are testing out GNOME running on mobile devices, I made it shrink to that form factor as well.
Have at it!
