Hello,

I’d like to submit a feature request based on a recurring issue we see in long-living editorial InDesign documents.

In some INDD files, font changes become impossible even though the UI accepts the change — the document internally reverts it due to broken or legacy font/style references. This typically happens after documents have passed through multiple InDesign versions, operating systems, or workflows (sometimes involving InCopy). At the moment, the only reliable fix is a full IDML round-trip, which effectively rebuilds the document and clears these ghost references.

It would be extremely helpful to have a built-in “document sanitize / rebuild” command that performs this internal cleanup in one step (essentially an IDML-like rebuild without manual export/import). This would be invaluable for editorial and production environments working with long-term documents.

Thank you for considering this — it would remove a lot of unnecessary friction from real-world production workflows.

Best regards
Daniel
