Methodox Tiffin
Methodox Tiffin (MethodoxTiffin.exe) is for reading what is finished and marking it up: it opens PDF, EPUB, Word, PowerPoint, Markdown and plain text, and annotates and edits PDFs. It was called Methodox Reader before it joined Methodox Office.
The Start Centre opens PDF and EPUB files in it, and the installer offers it as their default application. Word and PowerPoint documents open in Impulse and Expo, where they are edited; open one in Tiffin from its Open button, or from Open with in Explorer, to read it.
Starting
With nothing open, Tiffin shows Open and the documents you read last. A document given to it on the command line, or double-clicked once Tiffin is its default, opens straight away. If it cannot be read, Tiffin says why rather than closing.
Reading
The pages run down the window, with their thumbnails, the outline and search in the rail on the left. A link in the document is followed: a link to another page goes there, and the rail follows; a web or email link opens in your browser or mail program. A link that would open a file or start a program is named in a message and not followed.
Annotating a PDF
The tools in the middle of the toolbar mark up a PDF: Highlight (drag across text), Sticky note (click where the note belongs), freehand drawing and Rectangle (drag to draw a box). Delete removes the selected mark. Each mark carries your name and the time, and the Comments panel lists them; it opens by itself for a document that already has comments. Marks are saved into the PDF in the standard way, so other PDF readers show them as Tiffin does.
Editing pages
The organiser shows every page. Select pages and drag them to a gap to move them, or use the buttons that appear once something is selected to rotate them, extract them into a new PDF or delete them. The File menu also merges PDFs into one, exports pages as pictures and prints.
Undo and saving
Edit ▸ Undo (Ctrl+Z) and Redo (Ctrl+Y) cover every change to a PDF, marks and pages alike. Undoing back to what you last saved clears the unsaved mark.
Save writes the new file beside the old one and then puts it in its place, so a save that fails, because another program is holding the file or the disk is full, leaves the original as it was. Save As starts in the document's folder and asks before replacing another file. Closing the window, opening another document or dropping one on the window asks first when there are unsaved changes.
Settings
Tiffin keeps its recent documents and where you were in each in %APPDATA%\Methodox\Tiffin. On its first start it copies what Methodox Reader kept, so nothing is lost, and leaves Reader's folder alone.
