Also I saw your post (from 2007!) about setAlwaysOnTop being unimplemented on linux
I gave it a proper implementation while I was doing my work on child windows. Though I think setAlwaysOnTop would probably see less usage in a context where proper floating child windows are available (a lot of the usage of setAlwaysOnTop that I see is just people trying to achieve child window-like behavior)
But if anyone still needs it, it’s in there
