Mail.app plugin - a toolbar button

Question

How could I add a button to the Apple Mail's toolbar?

As i understand, I need to "swizzle" some methods of the MessageViewer class (this is the first responder window of the Mail.app). Thanks to several open source Mail plugins, I managed to implement a basic plugin that can display windows, sheets, react on events.. I also managed to get a class dump of the Mail.app that lists all of the classes/methods of the Mail.app.

I've seen several people claimed to have implemented this, also a free Mail Archive plugin adds a button to the toolbar..

Could you point me in the right direction?

Thank you!

I'm not sure what your problem is.

BetterDictionary is a Dictionary.app plugin I wrote a while back. Check out -(void) initToolbarItems method to see how I've done it (how the app gets there? +(void)load --> -(id)init --> -(void)initToolbarItems).
