I honestly think that the PROVIDER_LIST should be separated from the constrants.ts (as a JSON file) and a simple popup UI editor should be made to make adding more providers easy for anyone.

Edit: Created a feature request for this #559.

Please vote up if this is a feature you'd be interested in it and I can work on it.

Thanks.
