It works like the windows slider, only it looks better, has more options and it uses much less memory.
With the windows slider's max property set to 16777216 it uses around 70 MB of RAM and the program runs so slow that it's almost impossible to use, but with my slider's max propery set to 16777216 it uses the same abount of RAM as when it's set to 1 - almost none.
Try it and tell me what you think (source included)!
