Every thing that we use is open source, but I never saw any code of any applications that I use.
I propose that under help there would be an option: "view source code".
=============
This would be very good for all would be devs. I know playing with source code is BAD idea, but how did present devs learned to read it, write it and change it?
So wit this I also proposed an easy developers suite. In this suite there would be an sandbox where one could safely learn how to read source code and how to change it; from "hello world" to real programming.
This would bring Ubuntu and Brainstorm to new level, as user would not just demand new features, but would actively try to make them.
