Codeigniter 3.0 forced uppercase naming of controllers and classes

Dear All,

I have quite a lot of projects based on Codeigniter 2.1.

I'm considering porting them all to Codeigniter 3 and also consolidating Codeigniter 3 as my standard development platform.

One thing is blocking me, both practically and conceptually: the forced uppercase file naming of the controllers and classes.

First of all because I should change filename to many of my established controllers and libraries and I wouldn't like to do that.

Secondly, because having mixed case file names creates incongruence when developing on Windows (things that work on Windows but do not work on Unix in production) and these incongruences ater often difficult to discover.

Is there a way to configure or very simply patch Codeigniter to behave like before, allowing lowercase controller and class file names?

Thank you.

Stefano
