Why can Finder just show 7 different file infos in the detailed list view?
What if I want to show mp3 tags in the columns?
Let the user choose of much more file infos in detailed list view:
* mp3 tags (interpret, album title, ...)
* jpeg image infos (width, color depth, ...)
* owner infos, unix acls, ...
And don't make this available through the folder view options. Instead let the user right click on the column and choose from a list, like it's done in iTunes.
