Patch Tool Selection Fade

[Polycontrast]

In my workflow, I use the patch tool selection to fix large pixel areas. 

Immediately after the patch tool drag and drop gesture, I call the fade command to adjust the patch selection area.

The question is it possible to automatically add a constant fade value at the end of the drag and drop patch tool gesture? 

For example, after the patch tool drag and drop fade the selection area by 50%.

Please let me know if the question is clear

Thank you Jazzy, that is a fantastic script!

It does a lot more than what I had in mind and works great.

Many thanks for sharing the script!
