Lion Scroll Reverser v1.4.4 is for those that have trackpad but don't have the reverse natural scrolling selection option in preferences in order to revert the scrolling as it was in Snow Leopard.
To install, unzip and copy it to your Applications folder. To uninstall, drag it to the trash. Requires Mac OS X 10.5 or above.
Languages: English, Brazilian Portuguese, Greek, Italian, Spanish.....

So just open the zip, drop the plugging into your apps or custom plugging folder, double click on it and there you go is that easy!
The plugging will show up in the menu bar and you can hide it if you want. It will also auto start when login into system.

Tested on Lion 10.7.2 - "works perfect"

v1.4.4 - Fixed some small bugs and optimized improvements...

Features:

*Reverse Horizontal
*Reverse Vertical
*Reverse Trackpad
*Reverse Mouse
*Reverse Tablet

*Start at Login

Enjoy!
