I sometimes work between my iMac and Macbook and work from photos on a server in the house, one of the jobs i do is to tag photos with keywords. On my iMac i have made loads of Keyword sets for the various photographic styles, its a shame that these keyword sets do not sync on the creative cloud or through the Catalog file you have to start again on the other computer. Just spoke to Adobe and they explained that the Keyword sets are part of the program not the catalog. I think that this would be a nice feature for future software release.
