Why are Lightroom keywords listed in a linear line? I use Photools Image Management also, since the keyword structure is much better. I can have structural hierarchies, Like country, county, community, location, or type of relation to people. I get thousands of keywords, but can select from 20 top group names. This way it becomes much faster to find the right keywords, even when you do not remember exactly how you spelled it, or which keywords you did use before for that feature.
