@RASHAD,
Another very nice effect. Thank you.

Might there be some benefit in the effects to be combined in a single program to allow switching between them?

:mrgreen: Hi Rashad - you are hyper-productive these days.

What I would like to see is a high gloss effect for button shapes (circles, ovals, radiused corner rectangles). Pretty sure someone has already achieved it with PB, long ago, but it seems to have vanished.
