float window vs “relative” float quick ref bookmark panel

do I understand and tested correctly:
1- if I float a Scrivener window, it indeed floats above other app windows
2- assuming Window → Float QRP is checked, if I project bookmarks (⇧⌘ B) → convert to QRP, the QRP will only float relative to Scrivener, not relative to other apps which is unfortunate. It would make for a great note taking app. I find the scratchpad too basic.
It there are way around this ?

QRP = quick ref panel

thanks in advance for your time and help
