A plain pad for the JSON the other tools produce — poster layouts, paper notes, glyph sheets — and for anything else short enough to keep in one file. Type the mode in the top bar: json, js, py, css, html, md, txt. JSON is checked as you type; the footer says where it breaks.
| Gutter number | Fold or unfold that bracket; the pill shows the item count. Fold folds everything at once |
| + | Open a file from disk; the mode follows its extension |
| Save | Downloads the pad as a file named for its mode |
| ✕ twice | Clear the pad — the first tap arms it, the second empties it |
| ⌘Z ⇧⌘Z | Undo and redo |
| Tab | Indents inside the pad rather than leaving it |
The pad keeps its text in this browser and restores it when you come back, so it works as a clipboard between tools: save a layout from the Poster Editor, open it here, fix a value, save it back. Nothing is uploaded.
