Feature Request - Speed slider or increments

[adrianisbeast]

Feature Description

Instead of the silent/sport ect. system we have now id also like to have an incremental or speed percentage slider that you can use while you are printing.

Justification

i have owned printers with this (Flsun SuperRacer) for example, and really like this feature for testing how fast i can print and a lot more accuracy in changing the speed. a lot of the times i want a speed in between sport and ludicrous or reg. and sport.

Suggested Implementation

check out Flsun Super Racer UI for example, you can adjust speed in increments of 1% while printing.

(i cant find any screen shots rn)

Thanks!
