Windows 7 has a concept they call "Libraries." It's a folder that links to other folders. The "libraried" folder will display the contents of all the folders it links to. So if folder-A contains video of Jimmy's October Soccer games and folder-B contains video of Jimmy's November Soccer games, I can link folder-A and folder-B to the Library-folder and view thumbnails of all the October & November videos in one folder.
I find this useful and was wondering if it's possible to configure a similar thing in Ubuntu? It seems like I should be able to use mount to pull this off somehow but I don't know how.
