Templates & libraries
- Add template adds a company template, from an existing diagram or a file. Give it a category, and a space key to offer it in one space only. Up to 200 templates of 200 KB each.
- Add library shares a shape library with everyone: a draw.io .xml library or an Excalidraw .excalidrawlib. Up to 50 libraries of 200 KB each.
Integrity check
Start integrity check checks every diagram's page, file and preview image, without changing anything. Use Issues only to filter and Download CSV to keep a copy.
Re-index
Start re-indexing rebuilds the diagram list and search text from the files on your pages. Run it if diagrams are missing from Apps → Diagrams or search, for example after reinstalling the app.
