I'm not sure what you're talking about when you refer to the "18 most pressing lacking features"?
I've found Evernote to be a very useful tool, but use it almost exclusively on mobile (I have a Macbook which I use for development but don't use it much for personal use). I've found it hard to work with images as note attachments on mobile, and wonder why they couldn't a.) either be collapsible in a type of stack/outline as proposed in this question (which would kill a few birds with one stone), or at bare minimum allow the possibility of displaying images in the same manner as PDF attachments.
I'm not. I think the proposal in the original request would address my problems, and satiate the needs of others, so I think it is the best current proposal. And I do not see why it can't be done from a programmatic viewpoint.

I appreciate the suggestion, but this is not very helpful. I switched to Evernote to escape the nightmare of syncing .rtf and .md files to a Nextcloud server. This was doable, but subpar in terms of organization (and attachments!!!). Evernote bases much of its allure on the promise of its storage of attachments, emphasized by the release of the new "Scannable" app. I believe basic organizational methods for image storage and/or document organization are not an outlandish request.

Thank you... An imperfect solution, but better than nothing!
