[IPython-dev] Feasilibity of widgets/layout for mimicking this

Guys,
Thanks for the help! Nicholas, that's amazing; thank you for hacking this
just for our sake! That's really cool of you.
The mailing list was having issues the last few days, so I actually started
a github discussion on this thread. I'd just like to share that, where
Doug graciously helped me a great deal, and I posted a few followup
concerns. Obviously they may become moot with all of the cool stuff coming
up. Here's the link though in case you'd like to check it out and add
anything further.
As I elaborate on that link, the holy grail for us would be able to load
widgets anytime the user wants a GUI. These widgets would need to accept
input data, and return output data. For example in the example Nicholas
shared, I'd like the user to be able to pass in a matrix, calculate the
synchronous spectra, and then use that for further analysis in subsequent
cells in the primary notebook. Having that as a capability would be huge
for us, because we envision a mixed API/GUI workflow.
