Is this built as a Gnome Shell Extension? Would love to be able to just pop this into my shell on OpenSuse without having to change to an Ubuntu based distribution.

Also, what are they going to do once nobody is supporting Gnome 3.38 anymore, porting this to Gnome 40+ seems like it's going to be a pain in the ass. Hopefully it doesn't necessitate a Gnome Shell fork...

I don't know if the thing they're announcing here is just an extension, but the features mentioned in the article all come included in the pop shell gnome extension.
