Someone, who seems to have some personal knowledge of Snow Leopard, claims to have solved the mystery of Snow Leopard’s shrinking mail.app.

In a post that details the various myths doing the rounds on the shrinking apps—no PPC code (false!), smaller binaries (false!), missing language files (false!)—the writer spills the beans:

When you look in Mail.app you see that language files use up most of the disc space. Inside the language folder (e.g. “German.lproj”) are a lot of .nib files (the extension of Interface Builder). Inside normally are two files. One is a very small “keyedobjects.nib” and the other is very big “designable.nib” file… Now the “designable.nib” is gone. It seems like it had no reason other than to give hackers a chance to mess with the application’s UI design.

I guess he is referring to these two files which are inside each (c. 84) folder within every (18) lproj localisation folder, as in this example from the English.lproj GeneralPreferences.nib folder:

Perhaps this is as false an explanation as all the others.

Still, it has enough specifics, specifics that only someone with access to a build of Snow Leopard could know, to lend the story credence.

Jean-Michel took exception to a screenshot of my copy of Mail.app in another post about navigating around Mail with the keyboard.

He asks,

I’m sorry, but how old is that screengrab? it looks completely different to my mail.app, is this some of the hawkwings add-ons?

It is. I have modified the look of my Mail.app with two utilities that are easy to use and give (to my mind) a much nicer work environment. Compare these two interfaces:

First, the lozenges in mine (the front one) are gone, thanks to Mail Stamps. Now they are big, bold and brassy, just how I like them.

Harder to see but still noticeable, I have run UNO , system-wide theming utility for OS X that brings the unified Toolbar/Titlebar and lighter metal look of Mail and iTunes to all your skinnable apps.

I like the look. And, of course, once you get the taste for it, it’s hard to stop.

You can replace Mail.app’s Dock icon with one of the 295 alternatives on the Hawk Wings’ icon list, which also contains instructions on how to do it.

You can also replace the new mail badges that appear over the icon in the Dock with one of a number of alternatives.

Using the tips for hacking the Letterbox plugin, you can start to make changes to the nib files which control the layout of Mail.app’s message list and preview pane.

Lastly, if you are really keen, you could replace the mailbox icons with any number of improbable images that appeal to you. Use the Hawk Wings Hasta la Vista icon set, or make something better yourself.

Needless to say, no one in their right mind would try this without having backed things up first.

Go on. Take out the cleaver and make a Mail.app of your own!
