It would be really great if TextFlow would support selecting, cutting, copying and pasting text, just as a user is used to it from any other text control.

Certainly this is not as simple to achieve as with pure text controls, as non-textual nodes like icons could be part of the flow. Nevertheless, what a user typically wants to find in the clipboard after a copy action is not pure text, but may be an object graph instead. He could paste that object graph into a different TextFlow in turn.

Would be cool to have this in a future release of JavaFX. :-)
