Feature request: Add support for button property 'action'
On the Sencha conference in your MVC talk you promoted to use the action property for buttons, so we can easily reference them in the controller like button[action=addcontact]. Ext Designer doesn't provide a way to add an action value. If this is still the recommanded way, please add it.
It is possible for you to add any properties to a object. In the filter box above properties list, type the name (eg: action) and click the add button to the right.
