My understanding is that "window managing" tools like this are not possible due to how wayland handles information. Pro: More secure than x11, Con: I can't use wayland. Aside from investing a lot of time learning how to use a tiling wm I dont see how I'm going to get over my addiction to minimizing only the active window. ( xdotool windowminimize $(xdotool getactivewindow) )
For improved security with X11, try firejail+Xpra, or Qubes OS. They will not just help in the graphical front, but also others like processes and storage isolation.
