@ldl Because you have to override a Frappe class to add the additional views, this is something that can only be implemented in a custom app. If that’s the case you can also customize and export these cahnges via Customize Form instead of editing the doctype directly. This is not something that’s likely not achievable in an erpnext.com context or other hosted environment.
I didn’t get any feedback from the frappe team about the mod. It was really dependent on my other PR I sent to embed youtube videos etc, but that got closed without a real reason so I haven’t updated much on it. I have an updated version I’m using in my own environment but it’s probably not suitable for production yet. Thanks for trying it!
