Hm, I think this tool would've been really helpful for me in the past for a couple of occasions. Usually if I want to save a cell output, I just won't edit that cell and I'll create a new one, even if it means redundant code. Also +1 on keeping track of bugs! I should've added to the og post that one thing I do that's really helpful for me is keeping track of procedural knowledge (i.e. how to setup a GPU, how to fix common issue X, etc.) in a personal Slack that I've created as a second brain basically. I found that I used the message-yourself-in-slack feature a lot to keep track of small notes for myself, and since I did it so much, I created a whole private, personal Slack and that's been pretty useful in keeping track of bugs, etc.
Let's definitely catch up!
Yes! Especially if you show you have can provide relevant thoughts about their work, a lot of people will be happy to call or at least reply to some questions via email
