Erica and Shida what you guys have built is pure genius! I have used DOZENS of PKMs over the years, and written several (mostly for myself) one that grew to 40K lines.
I think Obsidian will be the last one I ever use… It has the right core features, and it is open enough. And it is just brilliant! It shouldn’t be that hard to get a general purpose PKM right. Except it IS hard!! Look at how many broken ones have come before…
Please do find ways to earn enough money from Obsidian to offload the parts of this job you don’t love, so you can focus on your little ones (both your biological one, and your digital one too 
)
