Lion Tweaks is a simple, one screen app with a list of the changes it can make with a Yes/No switch besides each one. Here are some of the things it can change:
- Disable Spelling Correction.
- Enable permanent scroll bars
- Remove window animation.
- Remove the fancy pants interfaces from Address Book and iCal and return them to regular windows.
Lion Tweaks is free but the developer takes donations. (Remember, this guy is 16 years old-- toss him a buck or two!)
NOTE: The major change in scrolling direction is not included in Lion Tweaks but you can lean about turning it off here.
