Request: Range slider
As we know that tkinter by default lacks a range slider widget which I guess is possible to make with tkinter. Though I found a module which can do this in tkinter called the RangeSlider, but it would be great if this feature is implemented in CustomTkinter too, hence this is just a request for a feature that might make CustomTkinter better and more unique.
(This is a screenshot of the RangeSlider module used in tkinter, you can see how it looks),
I would love to have a range slider, so +1 from here! Further inspiration can be found in Dash's RangeSlider.
I hacked a range slider that is vanilla to the customtkinter in opose to the mentioned package. I did not want to modify the installed package on my mashine so I put it in an extra file in my GUIs directory and imported it alongside the customtkinter module. As far as I tested it works just fine. I'll leave it heare, maby it finds its way into the module some day:
import math
import tkinter
import sys
from typing import Union
from customtkinter import CTkCanvas, ThemeManager, Settings, CTkBaseClass
class CustomDrawEngine:
"""
This is a custom version of the core of the CustomTkinter library where all the drawing on the tkinter.Canvas happens.
It is tailored towards the range slider.

@Akascape right as i actually used it i found a bug but fixed it and updated my previous comment. If I find the time I'll fork and arange a pull request but for now this will have to do. Unless @TomSchimansky you see it making it into 5.0.0 then I'll do what I can to get a pullrequest ready.
Great work @EN20M, really appreciate the hard work in making this!
I have tested it and it is working properly just like the normal CTkSlider.
BTW, I found one small bug when configuring number_of_steps. It is showing a type error :
TypeError: 'float' object is not iterable
Other than that, there is no other issues.
Just made this range slider compatible with the latest version.: https://github.com/Akascape/CTkRangeSlider Thanks, EN20M for providing the DrawEngine.
