Which applications should be in the Utilities folder? A while ago I wanted to make things more convenient so I organized the my Mac applications in folders. Little did I know, it prevented Software Updates to detect needed updates.

Now, I've been trying to revert things the way they were. For most Apple application, thats easy, just put it at the root Application folder. However there is the "Utilities" folder, that I played with a bit.

Which application should and should NOT be in this folder?
