this is amazing piotr 
I always wanted embedded youtube links and the option to control the iframe options too
Is there a possibility of putting the iframe option into a hotkey as well? (e.g. press a hotkey to turn on / off the iframe view)?
also great idea on embedding dynalist inside of dynalist, I’m not sure if I’m going to use it (too many computer resources used), but its definitely something I’ll play around with 
Also I wrote a list earlier of what you could embed with the iframes in this post previously, if you guys want ideas (bottom of the post)
I think for what I will be using this embed code support for now is only going to use youtube and possibly airtable + airtable forms for now , and maybe codepen.io. I’ll probably use run some search paramters like “<iframe width” so I know where I put my embed codes in document
