I have to say although I'm a #Qtile#Wayland user I try to keep up with the development of #RiverWM as this is definitely the window manager to watch.
What would make it near perfect for me but you may disagree is:
1: A riverctl rule to open a matching appid or title at a set position / size.
2: A sticky rule that instead of making the app available on every tag which to me would mess with most status bars. Something that would stick that app to a set output or maybe the currently focused.
