Notebook review tool

[Kyle Smith]

I'm just discovering deathbeds and I'm excited to use importnb for future features. Always excited to see people building on the notebook ecosystem.

I noticed you all aren't using a notebook review tool and just wanted to suggest GitNotebooks. Your latest pull request can be viewed here: https://gitnotebooks.com/deathbeds/importnb/pull/143

Keep up the good work!

Thanks, good luck.
