Thanks Observable Team! 
Having the embed cell generator accessible from the notebook menu is super convenient. I really appreciate it.
One UI tweak that I feel would be really helpful is if, upon clicking first ‘entire notebook’, one could then start clicking off specific cells–like being able to ‘opt out’ rather than just ‘opt in’.
I request this because I tend to have notebooks with a lot of named cells, and usually I wish to embed most of them without embedding the entire notebook. And toggling on each independently is a pain.
It would be very nice if clicking ‘embed notebook’ would toggle on all, and from there I just de-select what I don’t want to show (like where I require D3, or where I have an isNumeric
function that I don’t wish to expose).
Oh, and while I was writing this, I also see that the notebook credits are generated by default.
Jeremy’s Handy Embed Code Generator had this as a click-on / click-off option as a final step (“Add a link back to the notebook” ). Since I’m requesting UI tweaks, I’d also suggest bringing this feature into the UI – especially for iFrame embeds (I realize I can just edit it out when selecting JS + runtime embed).
For context on this second request from my own use cases: I am often embedding my link-shared notebooks into HTML papers that I pass around the office, and I neither want this accreditation to be repeated a dozen times for a dozen different charts on one page, nor do I always want to expose my notebooks so easily (sometimes it just raises too many questions).
Thanks for this awesome feature!
