This has been a serious problem since macOS Tahoe. Whoever signed off on the UI for Tahoe needs a serious schooling in UI/UX design principles - it's incredibly hostile to users. Not only does it make it impossible to distinguish between overlapping windows as this tool seeks to mitigate, there's many confusing UI elements and lack of contrast not to mention why it has so much padding on everything - you're left with far less usable space.

Somehow it's so cute that the name of the app is, well, a name.
