hey @Paul_Danyliuk, great stuff here as always. Sorry if I am overly self-promoting here, but would love to get this native in Coda, and I just added some commentary to that effect over on the other MindMap thread:
Unfortunately I don’t think my Coda abilities would allow me to use your solution without slipping up, but really amazing to see you can actually already do this in Coda. It is a huge item on my wish list!
