Instructions activities now support basic rich-text formatting - bold, italics, headings, and bulleted/numbered lists - with a WYSIWYG editor when creating them and matching formatted display for readers on both web and mobile. Links, images, and raw HTML still aren't allowed for safety. Survey and discussion activities now show whether your response will be shared with the journey or kept just for you. You can now choose and change a highlight's color right from its comment box, and your last choice becomes the default for new highlights during that session. The journey screen now highlights your next activity with an accent ring and adds a "Continue" button (or "You are all caught up") pinned to the bottom, so it's always obvious what to do next. Guides can now see a user's reputation while they are joining a Journey. Your profile page now shows your reading and writing points alongside your reputation.
