It would be nice if to have a feature to display connected records and form inputs in the same page or view. Right now when you add a list view knack asks you to display connected records in the new page but it would be great to have them on same page and also add connected records with a form on the same page. .
Simple Use Case
If you have a news post table and comments table connected to each news post. You make a list view for all news post and the below each news list item you have a new list of all connected comments and below that you can have a form field to add comment.
