- markdown read with pulldown-cmark: marks for live styling, blocks, links, words - forms::Highlight gains weight, slant and strike; measure and paint share runs - Inter Italic embedded, so emphasis reads slanted - forms::mention's popup and keys become Suggestions, shared with the editors - RichTextEditor with FixedFormatToolbar, the floating toolbar, LinkEditor, @ and : suggestions, WordCount and ReadingTime - MarkdownEditor: visual (a pressed block opens as source), source, split - BlockEditor: prose, lists, to-dos, quotes, callouts, toggles, code, math, diagrams the app draws, dividers, tables that grow and merge, pictures to resize and align, cards for video and pages, columns, synced text; slash menu, markdown shortcuts, handles that drag and open a menu, one undo for all - TodoItem and Checklist - icons: heading-1..3, workflow, merge - gallery: the Documents page with scripted states
