More important than views Rainmeter letst you put stuff floating on top of everything, make it semitransperant and let it move it out of the way directly or with some mouse/key combination.
Is this something that the designers of Wayland did not think of or is there a similar thingy for Fedora 43 KDE - Plasma? (or should I vibe -code one?)

It looks like there is a cairo-dock package available in the Fedora repos, but you should probably experiment with it on a spare computer if you want to try it.
