[Feature Request] Barcode support

[frank20a]

I would like to be able to quickly search for items marked with a barcode. This could be a specific parameter of an items that gets autofilled with a unique string or number for example. This could already be implemented by adding such a field to a template and populating it manually with a unique code but functionality to quickly search for it is missing. Ideally a common barcode scanner prefix key combination would activate the search bar and upon entering the barcode data the website would open the first and (if everything is setup properly) only result. The user could then export a list of their collections on a CSV file for example and create apropriate labels using the barcode field.
