When DragThing was finally left behind—after 24 years of service—by macOS Catalina’s lack of support for 32-bit apps, I knew I’d miss many of its features. I missed its (optional) modification of the Mac’s window-layering policy so much that I made my first Mac app, Front and Center, to replace it. My second Mac app, SwitchGlass, also replaces a feature I miss from DragThing. (Thank you, James Thomson, for unwittingly kickstarting my Mac development efforts.)
