works fine and all but i'm struggling to figure out how the per-channel setting works, because it never seems to save the speeds i set

Better than the other add-ons, but you can't get any fraction :/ Is there a reason why all these YT speed controllers don't support (more) exact values?

Would love for this extension to set a constant playback speed so I don't have to toggle it everytime I watch a new video. Thanks for making it though!

Very simple, does one task very well. As such the design could be improved integrating better into the youtube interface. What it lacks the most is instead of always showing 3x in the bar it could show the actual speed of the video.
