Thanks, Kirk! Another few questions that should be easy:
1. Is there a way of searching for all tagged photos in a catalog?
2. When a sync turns up missing photos, that means that it's in the catalog but the photo itself is no longer there, right? So is there any danger in doing a remove-and-delete? In other words, there's no chance that could somehow remove an actual photo, right? I'm confused because there are some photos that show up as missing, but nothing in the path or in the filename is at all different from what it is in the actual folder where the photo is located. How can this be?
3. In the sync collection, there is absolutely no reason to worry about photos that have shown up in previous syncs, right? Just clean out the current missing ones and all is well? And is there any reason to keep the old syncs at all?
