Hmm nice, I'll add that one liner next time I'll be editing that file (which will be soon as we want to automatically download the pdf with those QR codes)..

And regarding Odoo...I'm not really too happy with it, I've searched a bit and it doesn't seem to be widely used ...so there won't be a huuuge benefit from being familiar with it...but yeah, that warehouse management module which is already implemented for Odoo comes in handy and saved us lot of work.

Edit: Also, thx for the review! :D
