Floating Sleeve 2 (Music Player) window is ignored in App Layouts

[Coder84619]

I'm trying to use App Layout to position the "Sleeve 2" (Apple Music wrapper) player window. However, in the list of apps in "App Layouts" the floating Sleeve 2 window is not listed. It only shows the Sleeve 2 preferences window. Can the floating Sleeve 2 player window be positioned?

macOS Ventura 13.5.1 Rectangle Pro 3.0.6

Thanks for reporting. At the moment, windows above a certain level are purposefully not positioned because there are a number of apps that will break in strange ways if Rectangle Pro interacts with their windows that are above a certain level. Additionally, it doesn't typically make sense to detect windows above a certain level because these are usually system windows (things like alerts). There are very few apps that are floating at these levels (apparently Sleeve 2 is one of them), so I'd have to build in an exception for it. I typically don't build in exceptions like this, but would consider it with enough demand.
