Enhancement Request - Fine grain control of speed/pitch

**The Request**

The current implementation is great, but it would be excellent if you were able to control the speed/pitch by a granularity of 0.1. It currently allows a granularity of increments of 5. For example, this would allow you to set speed/pitch to 98.2% instead of only 95% or 100%

**Alternatives considered**

Being able to enter the percent (i.e. make the labels textboxes?) would make it easier to fine-tune the value and would fix the issue you have with controlling track and global values with the one slider (because both T and G would have their own entry mechanism).

On a side note. There is a demographic of people out there looking for a way to convert Spotify tracks from a=440hz to a=432hz. This change would allow them to get close to it (it just requires a pitchdown to 98.18181818%). This would probably prove pretty popular.

Thanks
