Disappointed in one major change to Lightroom 4 form the previous Versions. When in the library Module, I have smart collections created for specific color labels for filtering out images within a folder(s). In previous versions, when multi selecting a folder or multi folders and then also selecting the smart collection, for example "Blue" It would filter out all other images within the folder or folders to only the blue labeled images. In Version 4, it does not work the same, as Lightroom 4 COMBINES (does not filter) the images in the entire catalog that have the color label along with all of the images in the folders. Very disappointed and hope Adobe will correct and go back to the same library filtering as previous versions.
