[IPython-dev] Notebook extensions

[Juergen Hasch]

Hi,
thank you for adding extensions to the iPython notebook. I think this is really useful.

It allowed me to add a feature I always wanted to have in the notebook: breakpoints.
Now I can easily set a breakpoint in a code cell and execute from the current cell to the cell with the breakpoint set.

Here is the extension:

There is one question I have: Is it possible to restrict the checkboxes that are generated using 
CellToolbar.utils.checkbox_ui_generator() to codecells only ?
