Custom Speed or Increase Speed upto 3x [Request]

Hi, 
This app is perfect for my use the only feature that I require is custom speed if it can be set by user like 2.1x or anything, if that is not possible at least max speeds up to 3x like 2.25x 2.5x 2.75x and 3x, rest everything is fine with the app and fits for my use perfectly.


Thanks
