eek. That’s a shame. I was going to suggest the same thing as felgall. I figured it would be the least disruptive to how things currently work. Something like…
var baseConfig = {
'ck': '...',
'nk': '...',
'etc': '...',
};
var videoPluginConfig = Object.create(baseConfig);
// reading ck inherits from base
console.log(videoPluginConfig.ck);
// writing ck affects only videoPluginConfig
videoPluginConfig.ck = 'special_context';
