This new beta includes a very useful change—you can type a hotkey combination in any app and bring Huevos to the front instantly. You can change the combination via the Preferences window.
(Note to Cocoa developers: the HotKeys API is a Carbon API, and I didn’t know how to access it from Cocoa—until I saw this helpful post from the Unsanity folks.)
Huevos remains open source (BSD license). You can download the latest source code from the beta page.
