There's a new Lily beta available tonight.
This beta addresses a number of usability issues- there's new easier to navigate menus, a help screen, a contextual menu, an expanded status bar area with more info and better feedback, rewritten and expanded help text and newly redesigned and annotated help patches. This beta also has a couple of interesting new menu items: "Save as app" and "Save as addon" that allow you to save a patch as a standalone Xulrunner application* or as a Firefox extension. There's also 50+ bug fixes. And there's an icon now. Yay. The complete changelog is here
If you've signed up to test Lily previously, you should be receiving an email tonight with the new download url. We're still looking for testers, so if you're interested please get in touch.
