Super Video Speed Controller

I really like this extension, but I think there are ways to make it even better. Suggestions: 1. Can you allow custom keyboard shortcuts for the speed up and slow down and also allow custom intervals (like I would prefer it to go up/down 10% rather than 1%) 2. Can you had a shortcut where theres a saved speed. Like Maybe the G key or whatever automatically goes to 2x speed. etc Thanks for making this

it worked perfectly on almost every sight I used it for and I could save so much time watching anime on 4x speed (notice that this sentence is in past tense it hasn't worked since the newest update hop that gets fixed soon cause I don't want to watch stuff on 2x speed)

I liked this extension, however, it never works when I want it to. It works immediately after downloading, then I try to use it again and it doesn't work and I have to remove it and redownload the extension. Other than that the extension is great!
