[FEATURE REQUEST] Add slider as new input type

[sundevista]

Is your feature request related to a problem? Please describe. My feature idea isn't related to any problem. But it's simplify the number-based VALUE inputs.

Describe the solution you'd like I have a lot of VALUE variables in my quickAdd those created for storing numbers. And it would be nice if I have the ability to use sliders to input number value.

Additional context There's no additional context.
