With the complexities of the bindings, and the crossreferences caused by messages, projects become difficult to trace.
I was talking to the IT guy at work, and we both agreed there needs to be some form of folder that can store descriptive text / comments like a read.me file commonly found with many zip programs.
It could go near the scripting dropdown in the project folder, allowing multiple named sheets of descriptions to be left there. It would not be code, just text sheets. Bonus points for allowing full wiki type markup and linking between these comment sheets though
