[IPython-dev] Open-file dialog in the notebook for data files

[Adam Hughes]

Oh, ya sorry, I don't think there's a widget (AFAIK) that could pop up a
file system browser.  While there are pre-existing widgets like that in the
Traits library, they're probably not supported by the lighter Traitlets
library on which Traits is built.
