Feature request – editable titles in chart windows

[jpolitz]

It would be useful for students to have a way to edit the title in the window GUI that allows selecting xmin/xmax and so on:

One design would be to put the editable text box centered at the top, and then render it into the to-image at the end.

Another would be to have a text box off to the right for title, and on clicking "redraw" it gets rendered into the plot with the title.

I like the consistency of having the text box off to the right, to preserve some WYSIWYG behavior
