We should have the ability to set a preview length for articles. Also, we should be able to toggle between the preview length and full length in the feed.
Right now, when you post a long article it automatically shows the full length on desktop, and a preview length on mobile. On mobile when you click 'more', it shows the full article but there's no way to go back to the shorter preview unless you reload the entire page.
This is very messy in the feed; there should be some type of 'close' at the end of an article that reduces back to preview size.
