Thanks a lot for collab, I have access to really powerful compute from my job yet I still find myself using collab a lot. The only problem I had with it was the very vague FAQ and the spotty resource allocations but the new faq is much better. Thanks again!
I'll take the opportunity to request better editing ergonomics: the ability to connect from Jupyter/notebook-supporting editors and IDEs; the ability to open/edit .ipynb files from the local disk and/or Github without having to first put them on Google Drive.
Colab/Jupyter and friends are reinventing many wheels around editing code, and it would be nicer for them to support tools like Jupytext.
