How can you have Lightroom display nested structure of folders as in Aperture? If you create folders US and Europe and in each of those folders, you create folders, 1960, 1970, 1980, etc., within each of which you have bunch of photos. Lightroom would display the folders, 1960, 1960, 1970, 1970, etc. which does not allow me recognize their contents, Unless you name them US_1960, US_1970, etc., which defeats the purpose of nested structure to make the whole thing simpler. Any better idea?
