Feature Request: Allow multiple productID/vendorID pairs

[raman325]

Hi,

I have keys from multiple manufacturers and to use this application effectively, I have to change the Product IDs and Vendor IDs each time which makes the process relatively painful and causes me to rely on primarily one key. Is it possible to support multiple product/vendor ID pairs?

This likely requires a major refactor of the application data structure and UI
