Drag an application, or a whole folder full of them, into the image frame, and if there's a NIB file anywhere in there, and it can be "manibulated", you will see it in the pop-up menu, and you can save it as an editable NIB file.
It's not really decompiling the NIB, the program just happens to have an empty v2.X format NIB stored internally it can use:
- If the source file is a single file, we copy it into the internal nib as keyedobjects.nib.
- If the source file is a bundle, we copy it to the destination and populate it with classes.nib and info.nib from the internal nib.
