Are you on the latest version 0.9.3? If so which operating system (I'm on Win7 pro, but as long as you are on 0.9.3 you should be fine)? If you are in 0.9.3 make sure you have network access (because it needs to get to github to update the parts data base) and then in Fritzing run help->check for updates (which will check github, this is supposed to be automatic but I just had a case where mine missed an update until I did a manual check). The 4011 part is a late update, around November I think. Once the updates complete (if they are needed) then entering 4011 in the parts search window and hitting enter should come up with 4 parts, A microchip dsp, the 4011 single part the 4011 multi part and another dsp. As to editing parts as I said intitially it is exciting. The new parts editor is a work in progress and not entirely finished (I rarely use it, and tend to create parts entirely outside of Fritzing and then import them to be blessed). The graphics for both breadboard and schematic are in svg files and they are typically edited by Inkscape (open source and what I use) or one of the commercial packages such as Corel Draw or illistrator. The tutorials listed give the gory details Image may be NSFW.

The parts editor allows you to make a generic box like schematic for cases where that is acceptable, the real logic diagrams need to be created in an svg file.As to the files, if you are on Windows (as I am) then the user files are in a hidden directory in c:\Users\user_name\AppData\Roaming\Fritzing and c:\User\user_name\My Documents\Fritzing. (where username is your windows username) To see at least the AppData one you have to enable show hidden files in explorer. The paths for the other OSes are in the documentation somewhere (I can find it if needed).
