I primarily have the main window in its "optimal size" in the center, and some other windows scattered around in the “peripheral vision”. The Desktop has to be always a bit visible for drag and dropping stuff into/from it.

@rafa do you have a tool to always get it to be there? 😅 I like having windows a little smaller on large screens, but it bothers me to no end when they’re not perfectly centred. 🤣
