macOS QuickLook - Problem when exporting Flows

I just noticed a small problem with macOS QuickLook in the following circumstances:

  1. Create a project with multiple flows
  2. File → Export → Flows…
  3. Export Flows as separate files or select one or more flows

If you now switch to the finder and look at the QuickLook previews you’ll notice they will still show all Flows though once you open the file everything is correct.

That’s right. The Quick Look plug-in looks for an image preview saved within the project. Dorico saves a preview of the first page of the active layout. But when you export flows, Dorico never actually “shows” the first page of the active layout for each of the exported projects, so it doesn’t get the opportunity to save an appropriate, different preview image in each project.
