Learning the tool for the first time was extremely difficult, and it could be because of all the other processes we had around it. But knowing you can do these things in batch, you can do things in the foreground or online mode, and then these, you have to have a package for. There are these rules, and some of the concepts inside the tool are not clear, like what is the CCID? Why do I have to have one? What is that? And how is it used? As a developer, it's not important to me - I don't know what a CCID is, and I don't care - but apparently it's important to someone.
