There's also a program called ResKnife in development. It's still rather early on, but it gets the job done for basic tasks.
I don't, however, think that either of these work with ResEdit TMPL's, and almost certainly won't work with NovaTools.</STRONG>
Resorcerer has indeed been carbonized, and those apps can all be used for .rsrc files but those aren't used by some newer apps.
Kent, editing apps in OS X is a bit of a different game, and a much more fun one at that

In OS 9 you'd just have one application and you'd open that in ResEdit and if you were lucky, the resources you wanted to edit were in there.
Now with OS X, the newer apps, and almost all the bundled apps, are bundles. So Mail.app isn't really just an application in the generaly OS 9 sense, but a folder that acts like one. If you control-click on it and choose "View Package Contents", you can see the stuff in there. Most of the goods are in /Contents/Resources/
With Cocoa, basically all images used in the apps (that aren't rendered of course) will be in /Resources/ as .tiffs (generally). So you can just modify those. If you have the Developer Tools (connect.apple.com) which is strongly advised if you want to go about hacking, you can even modify the nib files. They'll be in /Contents/Resources/English.lproj or whichever language you are editing. You just double click on the nib, and from there you can move text fields around, resize the windows, and modify the interface really any way you want. This is the best part

Make sure not delete an existing text field in a nib and replace it with a different one.. just modify the existing one. This is because almost all the objects have connections and need to remain intact. This goes for all objects, not just text fields.
Oh and just like before, always work on a duplicate! I hope you find this enlightening and fulfilling
