No Mail.app Animations on OS X 10.9 Mavericks and 10.10 Yosemite

A Mailbundle plugin to disable the Mail.app Send- and Reply-animations on OS X 10.9 Mavericks and OS X 10.10 Yosemite. Run on your own risk. When having issues, please remove the Mailbundle again.

How does it work?

This Plugin disables Mail.app animations in 10.9 and 10.10 by swizzling Mail.app's -[DocumentEditor shouldDoPopOutAnimation] to return NO always. To disable the send-animation, we swizzle -[DocumentEditor _performSendAnimation] to directly call -[DocumentEditor __sendAnimationCompleted]

1. Copy AveNoAnimationsInMailPlugin.mailbundle to ~/Library/Mail/Bundles/
