Marking which photo was shared/uploaded on social networks. With so many social networks and photo sharing services, it's very hard to keep track of which photo was shared on which online services. I would love to have a feature in Lightroom where I can manually mark on which social networks a photo was uploaded to. There are so many social networks and new appearing constantly, so I would like to have an option to add (and delete) social networks to the list and add myself a small logo of a social network. Once I mark a photo shared to XYZ service, a small logo of XYZ's service could show up somewhere.
