Note: There is a slight alignment issue caused by these modifications in the General tab because of the way ConfigTool is setup, everything in the different tabs is right-aligned unless it is forced to be left-aligned by something like a QLineEdit.

Yeah if you want the uppercase here then hardcode it. The NAME variable's meant to be the package name so.

Or if you want to be cleaver maybe Python has a str.uppercase() kind of function that only does the first letter. Then you could do something like NAME.uppercase(), I don't actually know if Python has a method that only uppercases one character but just a thought.

I'm fine with either routes so I'll leave the decision to you.
