Context
When working on your page(s) it could happen that you need to add a new attribute to your page. Now you need to go back to your domainmodel and add the attribute , then retrun to your page and add the attribute there.
Idea
It would be convenient if you could add the needed attribute (with a dialog, directly to the entity) from the page you are working on. For example directly from your 'Connector' tab since this is the current representation of the entity you are working with.
