Helpful settings catalog of Create Texture Draw Options.

[tkbd]

I'm looking for a way to have a kind of patterns library to make that shareable as well as minimise the work every time we need an previously used setting.

Micheus, In your HeightMap plug-in, there was a function that choose from a preset of gradation styles.
It was very useful!
So,I hope similar function that can be invoke preset shader style in few clicks.

Another idea ... CUI/Web browser way.
This does not manage the preset list/savefile. Just read the settings just through the configuration string.
When press a "Get" button, It will generate a configure string from parameters from GUI Elements.
When press a "Put" button, It will be automatically GUI is reflected from the contents of the text field.
However, Programmer does define an argument for parameters to be used,and should to sanitize a input string unexpected.

This Config string method is adopted in application jPDFTweak.

P.S
Thank you for adopting the type names of Hexagon.
Also, I'm glad the new shaders and parameters are added by your update.
