For Color Swatches Plugin, when update made to attribute, it should update all
As is, the swatches plugin does not automatically update attributes on products. For example, if I add a new color to my swatches, this doesn't get added to my products that have "All" colors selected. I think it should, because as is I have to manually add this new color to 300+ products. It's a pain. It's safe to assume any product that has "ALL" selected will be using whatever color gets added in attributes.
