Has anyone figured out spool management on Klipper? Would be SO useful

I really miss the Spool Manager plugin from Octoprint. It was so cool to be able to track prints by spool and monitor remaining filament. Miss that.

Has anyone figured out anything similar in Klipper? The only thing I’ve found for Klipper that might provide what I’m looking for is below, but it seems somewhat stalled. Anyone (much smarter than me) want to work on it?
