Display all variables

[BernhardKonrad]

To avoid confusion with what variables are currently defined we could add a button with something like

import pprint
pprint.pprint(locals())

Or even better, display (a filtered version of) this output in the side-bar. If real estate becomes an issue maybe a filtered list of the keys is enough.

Adapting something like the approach taken in this widget example might be a good way to get started here: http://nbviewer.ipython.org/github/ipython/ipython/blob/master/examples/Interactive%20Widgets/Variable%20Inspector.ipynb

The variable inspector widget is fantastic! Is there a way to execute this python code without pasting into a new cell, execute the cell, delete the cell?

[ivanov]

sure, use IPython.notebook.kernel.execute("stuff to execute goes here")

[ivanov]

but actually, that might not work, because that might not get the response back on the page and into the widget area...
