Grasmere 1.3 is for writers and researchers taking a project from idea to finished manuscript. PLAN • Save Web Page: keep a web page's article as a clean Markdown document in your research folder, with where it came from and when you read it. • New Source: look up a book by its ISBN or a paper by its DOI. DRAFT • Citations: type [@ to cite a source. Exports format them in APA, Harvard, Chicago or MLA, with a reference list at the end. • Brainstorm: the new name for New Document with Questions. • Diagrams from Mermaid code blocks, and colour in code blocks. REVIEW • Send a document or a whole book out as Word. Bring your reviewers' copy back with File ▸ Import Review, and every comment and change appears beside its passage to accept or reject. Edits made without Track Changes are found too. • Restore to Before the Review puts everything back if you change your mind. PUBLISH • The Manuscript view: see a book written across many documents as one, reorder its chapters, and export it as a single PDF or Word document. Also: Shortcuts actions, front matter you can edit in the margin, an optional Markdown check, and many smaller fixes.
