Well, this was fast! Thanks for implementing exactly what I was looking for! One small downside however: The first scan I did, everything worked fine. The barcode info was added to the search link for the different providers, and I could click one, and it would work. However, when I do a new scan, the code from the first one still remains in the search link, so my results always show the product from the first scan. Closing, and then reopening mBarcode does not fix this.
