The New UX is great and what really differentiates it from the old UX are the ability to use icons and images which can bring a boring app to life. A massive drawback is that Anaplan forces you to store images outside of the workspace typically using third party services like IMGUR, another drawback is that you have to pay for or download free icons from another third party service like Flaticon and then rework the icons to your App/company colour scheme. This whole process takes hours as you search for the perfect icon and then editing it and then uploading it.
It also has massive drawbacks - your company policy may prevent you from storing their images on third party services, you need to subscribe to those third party services so you need to share those credentials with another model builder else all is lost when you leave the company or get hit by a bus. Or you have to jump through hoops to get your company to host something where Anaplan can access your images. Similarly, if IMGUR (or the service you use to save your images) decides to charge you or goes under then say goodbye to your images and hello to a lot of UX rework.
Anaplan need to provide a simple service where you can upload your images safely and securely without overhead to your workspace usage. Anaplan should also start an image library where you can access thousands of generic icons and images, ideally be able to edit the colouring and easily link to your apps. Until Anaplan brings an image repository service in-house then this feature of the UX is not really viable for many Anaplan subscribers.
