We need the ability to have all images from a designated folder automatically displayed on a page in gallery style. Maybe something like {img-gallery} after linking the folder in markdown.

It would also be a good idea to have the "assets folder" selected on page creation for each page you make, where uploads in that page editor could default to. Or, as i've seen suggested elsewhere, auto-create assets folders which match the page names. We end up creating matching asset folders for all our pages anyways, matching in names, to keep it organized.
