is possible extend a plugin without specific filter or hook?
i have edit and make some custom code in a plugin, now I don’t want to lose the changes when this plugin needs to be updated. i think the correct way is create a plugin. I’m finding it difficult to create it. because the custom code is in the funtion in main class but if i extend the main class and copy the construct is like the plugin is activate the second time. what is the right thing to do? the plugin not have hook or filter for what i need.
