Libraries are one of the features I like about Windows 7 (admittedly, I haven't delved to deeply yet). Anyone using a similar concept on a Linux system? I figure UnionFS could work, but I've not played with that (yet).
So is anyone doing something like 'libraries' on Linux, what's your setup, and how do you like it?
About Libraries: My understanding is that they group different directories together into a single searchable/browsable 'directory'. For example, your 'music' folder could contain your music, the music in your computer's 'public' directory, and the music on a shared (Windows Vista/7) computer. As far as I know, they would be 'merged' together into a unified folder.
Update: The search utilities are good options; however, I'm also interested in methods that create an actual file system path, that can be used as the source in other apps (for example, group music from different locations to use in a media player). Sure symbolic links could be used, but I believe Win7 libraries show the contents of all directories in the 'library' directory.
