I work with various projects that each has separate collections, so I have my color swatches sorted accordingly into each collection folder in my CC Libraries for each project - which is great when I switch from Illustrator to Photoshop and other desktop programs. But on iPad version of Illustrator all swatches are in one huge messy mix of swatches without any kind of (sub)folders visible - I can´t believe that this basic functionality is still missing. Hope it will be improved very soon!
