Adobe Illustrator Swatch Management
Hi..Mac Users, please help. I have a simple question regarding organizing my Illustration Swatches.
Where can I delete the swatches I imported a long time ago? There's a section called: User-Defined from my swatch drop-down selections, but I couldn't find anywhere to remove them. (I went to Application/Presets/Swatches, but still couldn't find them...) Please see the screenshot 1. 
Another question is..I didn't know how to import .aco swatch to Illustrator so I use Photoshop export swatch to .ase so I can import it to Illustrator...(is this is the correct way to do it?)
But, I don't know how to remove them from the drop-down swatch selections. Please see screenshot 2.
