The hub for building and maintaining a document project - a file manager for everything that makes up the document, with each row opening the right in-app editor for that kind of file. Get here from the Projects list's edit icon, or the overflow menu's Edit Project Files.

The screen is organized into sections:

Properties

• project.json - canvas source (a physical base.pdf vs. a generated blank page), page size, background color, and editor guide margins. See Project Properties.

Template

• base.pdf - tap to preview it. See Create base.pdf for regenerating it.

Input

• form.json - tap to open the Form Editor.
• autocomplete.json - tap to open the Autocomplete Editor. Doesn't need to exist ahead of time - opening it with no file yet just starts empty, and the file is created the first time you save.
• presets.json - tap to open the Presets Editor.

Processing

• validate.js / process.js - tap to open the Script Editor. See Scripting & Processing for what these actually do.

Overlays

Every other layout JSON file in the project - overlay.json plus any additional partials referenced from process.js (e.g. a conditional logo or badge overlay). Tap one to open it in the Layout Editor.

Use the Add Asset button at the bottom → Add Overlay to create a new, empty layout partial file (just give it a name) - useful once you're ready to have process.js conditionally include extra content. See Layout JSON for the partial-file format.

Images / Fonts

See Assets & Fonts.

Deleting files

Every row except project.json, form.json, autocomplete.json, and presets.json (structural project files, not arbitrary assets) has a Delete option in its overflow menu - base.pdf included, once it exists. Deletion asks for confirmation and can't be undone.

Exporting the project

The share icon in the app bar exports the entire project as a .yatate file - a ZIP you can hand to someone else or move to another device. It excludes output/ (generated PDFs don't travel with a template export); everything else, including autocomplete.json, is included. See Quick Start for the import side of this.
