figures are not closed in a notebook...

[rvdboomgaard]

I really like the %matplotlib widget extension for the interactivity it provides. However, the transition from %matplotlib inline to widget is not as smooth as I hoped for:

• every cell that does some plotting should open a new figure (else a figure from a previously executed cell will be used)
• when you reexecute a cell (often done in notebooks, meant for prototyping and education...) a new figure is made AND THE OLD ONE IS KEPT... shouldn't the old figure be removed/closed to stay in line with the inline matplotlib option?
