I'm not a programmer, just a graphic designer and user so I can't talk about the code but just about the user experience. The extension does what it says. Is a free extension (remember this). Need a little time to understand how it runs but is not so hard, remember that a 36 feet sail boat is more complex than a 10 feet one. A bit of goodwill can help the users and however these guys work hard and are writing a new document system help. May be I'm lucky but all the issue I submitted on support forum have had quick and kind reply. Keep up the good job!
