"Select All Unused" - great command, "Add Unnamed Colors" - sometimes also useful, but shouldn't you expect "Hide Unnamed Colors" too?
And couple of things I really miss here:
"Find Duplicates" and "Sort by...". I always try "to keep things clean and simple" as much as possible, unfortunately, sometimes I get files from other designers with a real mess there... and in a Swatches panel too. Hundreds of colors, dozens of duplicates, some of them obvious, some - not. Everything scattered here and there, and... no way to get things a bit more organized.
Well, no more words: just look at the Links panel and its options! Things are much better here...
I agree. I like Illustrator's option of being able to sort my swatches myself with color groups. I too have the annoyance of having everyone else's swatches mixed in with mine when I syncronize my book documents. I just have to be sure to name all my colors. Having the swatches panel be more like Illustrator would be a big help in keeping things "clean and simple".
