Is there some way to make an iTunes for ALL files (instead of just music,) where I can add columns (for more sub-genres and stuff) and do instant searches for anything I put into this library? (Excel searches are NOT the same) Really, iTunes is a spreadsheet-style file-manager for music and movies. I want that same spreadsheet-style file-management for anything. I want to add new columns so I can arrange by different things I make up. In the Finder, I can't arrange things by genre; there's no column for it. I want to be able to make one, so I can sort that way. I also want many of the same columns as in iTunes, like Date Added and Comments; I use Comments to "Tag" my songs with specific moods or instruments (with a #hashtag like on Twitter,) for use in smart playlists or searches. The Finder already knows which programs to use for each file type, so opening a file would be outside this manager. Can this be done in Excel (including an instant search bar) or with iWork somehow?
