A Template Panel
Most important: have a new panel, almost exactly like the keyword panel, but instead of a list of keywords we would have a list of templates. That would be the fastest way quickly assign metadata the photos. User could see the list and chose the most appropriate template, which would then appear. It would be just like: Image > Metadata Template, slide mouse down to "arrow", click on arrow, look for best template and click on it. But it would do all this with one click, saving time, and speeding up the process for a smooth flow.
