Preflight

About this plugin

Preflight helps you spot breaking changes in your component library before you publish. It compares your current components against a saved reference and produces a clear report of what would break in existing instances.

Catches things like:

1. Removed layers or nested instances
2. Property removals or type changes
3. Variant options/axes removed
4. Layer type changes (e.g. FRAME → GROUP)
5. Component deletions

Workflow: save reference → make changes → run Preflight → review report → fix or document → publish.

Extras: run on file/page/selection, click-to-jump to the component, export Markdown / copy to clipboard, local-only storage, resizable UI.
