Editing parameters that show to users

I crated a filter (a Filter which I have been waiting for years someone to make before Filter Forge) and it turned to be funtionally okay. Problem with it was that with "Saturation Contrast"-parameter value to end user is allways 0-100. Or is it? Can it be changed to for example -50 to 50? It would be much more logical to use because negative numbers reduce saturation contrasta and positive numbers increase it. Now numer 50 does nothing and number 10 reduces saturation contrast by 40.

Is there way to change it and if not, could this feature be implemented?

Here is the filter if I did not made any sense:

...and other thing. Why all the examples of that filter are randomized? Why can't page use also presets that I made? Now those randomized presets do not give as clear impresson of filter as those I have made.

This is a current limitation of the control sliders. The devs are aware of this issue, and hopefully this will be changed in the future.

I know the remapping command and I use in that filter. I was not talking about that. I was talking about what the end user can see.

Thank you for the information and ability to read my poor english.

----The first 9 presets you make are on the filter page, just make sure *Seamless Tiling* (just above the randomizer at the bottom on the settings page), is checked when you make the presets, so they look the same on the webpage there. jffe

Thanks. I have to try that.
