I would be fine with fixing the directory structures so these can be the same.

It would require a lot of changes else where, but ideally we do something like this:

move templates/assets/plugins to src/plugins

The path would look like this: src/plugins/popup/popup-editor.html

So you can then update the views paths to match that: views/plugins/popup/popup-editor.html

Currently we store the popup editor in editors and plugin in plugins, but we can store the editor for the popup plugin in src/plugins/popup/editor and js file in one place.

I think this would make complexity of your overrides easier, and is probably a better location to store things anyway.

We can make this another ticket if you want.
