easy to use and remembers my settings, good job

Hello! This extension is quite good and i genuinely enjoy it, but i feel that the add-on have a 99% unnecesary number format Playback Speed... This is far the best and simplified Nightcore Pitch modifier i´ve had in Firefox so i would gladly give you a tip or something if you could minimize the number format to something way more simple (Slower: 0.8x, Slow: 0.9x, Normal: 1x, Fast: 1.2x, Faster: 1.35x) for example...
