Show active Launch configuration in RunToolbarAction

One of the things that bothers my in my usage of Eclipse IDE is that I never know what will happen when I press the Run Button in the Toolbar. Quite often I start the wrong thing. I noticed in other IDEs that there often information text is presented at the run button to give users feedback what will happen when the run button is pressed. I think this would also be great for Eclipse's RunToolbarAction.

For that I did first experiments and with little changes (i.e., add `mode="FORCE_TEXT" `to the action definition of RunToolbarAction) I could show some text in the toolbar. Where I'm now struggling is that when I try to update the text of the Action the action is moved as child to the drop-down.

Therefore I would have two questions:

1. Is this a feature that should be present in the Eclipse Platform?
2. What is the correct way to change the Action text of a toolbar item with drop down.

If the answer to 1 is yes I would be happy to work on that issue. However I may would need some guidance on 2.
