It is extremely complicated to change file names. Often time when downloading files I need to change the name. Having a file name and a document title is over complicated. This needs to be simpler, have "document properties" with file name ONLY (get rid of the whole document title stuff) on the left-hand menu actions. To me, this fiasco of changing titles and having two different names for a file is one of the things that make Adobe EXTREMELY inferior to other products.
