Application Enhancer 2.5b1 brings Leopard Compatibility
If you've been waiting impatiently (as I have) for a Leopard-compatible version of Unsanity's Application Enhancer, then you can rejoice: the wait is over!
A couple of days ago, Unsanity has released the first public beta of Application Enhancer 2.5, along with a beta of most of their Haxies (FontCard, MenuMaster, Silk, FruitMenu, and WindowShadeX). These all are accessible from this article.
Congrats, Unsanity, and thank you!
