Please make an EASY to find\access description of any and all "Idiot Diagrams == IdioGrams" used in you application. One of THE biggest pet peeves is using acronyms without defining them... using icons (and lots of them) without providing easy access to their meaning is no different.
Yellow square with ellipsis == Edited File?
Purple square with question mark == I have no idea....
Red square with dash == Deleted file???
Seriously a major issue in why I am considering switching to a different tool.
