Need a MUCH BETTER document editor

The Editor for Documents is very weak. It requires multiple clicks and menu choices and moving the pointer back and forth to change a single field, or add one to a document. Look at Robo 3T or 3T Studio for how they make editing a document so easy – just using just a normal json editor, including cut and paste and other text edit normal features.

For example if I want to insert a field object into several documents, why can I not simple paste in a valid JSON object as text and then edit fields if needed?
