Things people get wrong
Most are five-second fixes once you know where to look.
"I clicked a file in the tree but it didn't appear in the PDF"
Clicking a file in the tree just focuses it for preview, it doesn't add it to the plan. Drag it into the print plan in the middle, double-click it, or click the small + that appears on hover.
"Print made a 100 MB file"
The browser's print dialog defaults to your last-used printer. If that's a physical printer, the dialog produces a giant raster snapshot when you "save" it later. Change Destination to Save as PDF at the top of the dialog before clicking Save.
"My .gitignore'd files aren't showing in the tree"
They're hidden by design. Open Settings and turn off Respect .gitignore. Junk dirs like node_modules and .git stay hidden either way.
"Headers and footers settings is gone"
The page-layout button only appears when you have a project open. Headers and footers are stored per project, so the button is hidden on the empty editor state.
"I switched browsers and lost everything"
Settings, recent projects, and behavior-learning all live in the browser you used them in (localStorage and IndexedDB). They don't sync across browsers, devices, or incognito windows. Re-open the folder in the new browser; PDFy treats it as a fresh project.
"The TOC says page 3 but the cover counts as page 1"
By default the cover is page 1. If you want the first content page to be page 1, open the
page-layout sheet and set Page numbering starts from to 0. The page in {{page}} updates everywhere, including the TOC.
"PDFy froze on a huge folder"
Smart-add walks every code/text file in the tree on first open. For a folder with tens of thousands of files, that's slow. Disable smart-add in Settings and pick files manually. Or open a subfolder if you only need part of the project.
"It works in Chrome but not Firefox/Safari"
Those browsers don't ship the File System Access API. The editor route auto-redirects to the unsupported page. See browser support for the full list of what works.
