Packed javascript code in plugin?

I was looking over existing plugins to enable tabs in the editor, and checking out this one.

I stopped when I saw the packed code in the source.

I’m sure its most likely harmless, but I personally am scared away by any plugin that doesn’t include source code. Also, I’m pretty sure its against the terms of the Plugin Repository and the GPL.

Can you revise the plugin to show the unminified source code instead?
