There needs to be a way to Quickly add a tag (after one is created) to additional photos. In other words, once I create a tag once, I need to be able to add this same tag to many other photos (one at a time though) with the simple click of the mouse, or keyboard shortcut, or similar. Having to go through the process of adding tags (as I'm reading in the instructions) is too time consuming when dealing with 1500+ photos. End goal is to flag photos as "favorites", that others can see and also add flags/favorites, and/or sort by the tag to see just the favorites. (Or just as quickly as photos to a specified "collection".
