How about the ability to modify a dynamic property’s decription after it has been created? I often create a dynamic property to see if something will work the way I want it to. If I don’t write a description at the time of creation, I can’t modify it later. I tend to document stuff after I get it to work.
This is done for the next major version - you can now change everything about a dynamic property after it has been created. Binding references to it will automatically follow the new name. Scripting references to it will break.
