When editing in a diagram which may have servral thousands elements, just a small modify operation, such as: create a new element, change the property of an element, the representation style of all diagram elements in all opened diagrams will be refresh. Current representation style refresh mechanism is time-consuming, it will result in slow editing feedback, this is unfriendly and inefficient.

To be more precise, the full refresh of the diagram is done when executing a tool that creates a node on the diagram.
* in automatic refresh, a full refresh is done : every existing diagram elements on diagram are refreshed
* in manual refresh, a full refresh is done only if "force refresh" is set on the tool

If I understood well the enhancement, you would like to have a mean to not do a full refresh when executing a tool, EVEN IN automatic refresh.
