1) In the language designer you could set a property on a concept to prevent users changing colour size etc
3) Previously you could specify an object type (other than int etc) for a concept attribute e.g. make an attribute store HTML
4) The menu I am referring to is in the designer when you right click on the diagram. I used to have code to call my validation routine but now this causes an exception. I removed my additional code and the menu has duplicate items.
