I personally prefer a browser based CMS, as this would provide cross-platform capability. Elements is GREAT for concept, design, and creating fully static websites. By having an OPTION for a CMS “connected” to the cloud, the possibility of two-way synchronization exists. THIS IS A HUGE POWER FEATURE FOR ME!
I understand that an app would be capable of this too. But THAT is another app with its own development and capabilities to deal with.
