Cool, have you thought about having Lexikos integrating your "better" INI methods into the main Autohotkey? Are there any disadvantages to using your methods instead of the default IniRead and IniWrite provided by Autohotkey? If not - then lets have Autohotkey use these by default in IniRead and IniWrite!
This method over the built in ones have much more overhead if you're just reading a few settings out of a file. This library is built to handle large files where you're doing complex things with it (100+ settings).
It could be better implemented through a class in AHK_L but I don't have the time to work on that.
