What would it involve in Neos to render a button below or above a list of nodes (think blog posts) that allows to open a form to add a new node to the list?
Do you want it to work only from backend interface, so only website editors can add more posts, or on the frontend, so any users can create posts, after login?
I think that’s a very good idea, something I’ve been wanting myself for a very long time.
I think @robert did something like this for his blog, did you?
Try to gather more feedback from everybody and form it into RFC, I would support it, and maybe I’m even interested to work on this in some future.
Regarding constraints it’s a different question, try to ask around in our Slack or make a separate thread, it’s not really related.
