It would be super helpful if Swatch libaries (that are used in Indesign or Photoshop anyway) could be easily transferred to a user's Creative Cloud Libaries. It would be a great incentive to 'upgrade' my team to CC Libraries, because we already have legacy colour libraries that have not been converted over due to the massive time constraints of doing this manually, swatch by swatch.
There should be an option to upload a swatch libarary to CC libaries and then rearrange the files how you like.
Currently you have to manually add a swatch one by one, and its not even clear which ones are CMYK (Process) and which are RGB (Digital). There is no clear label (unless you hover over the swatch and wait 3 seconds for 6 characters of the colour properties to appear), unlike the old Swatch formats which clearly show a unique icon for Process or RGB colours. CC Libraries comes across as something useful for amateur designers with a small volume of assets or brands to work with, not something for the high volume professional.
