what happened to the file highlighter?
Prior to Mavericks when you wanted to tag a file or folder you could highlight it with a color. This gave a 2-dimensional feature to the file system and a heirarchal order. In Mavericks, this highlight function has been replaced with a colored ball or tag that sits next to the file/folder name. Why? The 2 dimensionality is now lost.
