Data items auto complete feature

[JohnSmith1]

I think it would be a great idea to have an auto complete feature in the expressions editor so if you start typing a data item or collection name it will suggest options based on the already created data items or collections within your process or object. and then if you press the tab key it will auto complete the name in the editor for you. I've attached a mock up to visualise how this could look. I feel this would save a little time but also it would make it simpler with less clicking involved.
