G'day Vic,
How is life there? I hope you are fine and your kitchen works are finished just like mine.
The main problem with the colour overlay option is that you didn't understand my explanation of the effect selector.I do appologize but it can be my fault as well. For the effect you marked the white square on left side, didn't you?
But have a look what'll happen when you clicking the name of the effect next to the white square. Do it now please. I'm sure you can grasp.
In that way you can access all effects there and settings for them.
