How many carousels can I create with Free?
You can create an unlimited number of carousels with Free.

Markdown Importer FAQ
Can it import tables and code blocks?
Yes. Headings, paragraphs, lists, quotes, code, tables, separators, and images become native blocks. Unsupported raw HTML is preserved in a Custom HTML block.
Can I add image files separately from the .md?
Yes. Pro has separate Markdown and image drop areas, and also accepts mixed drops. It matches filenames and places images at their referenced positions.
What if a post with the same title exists?
To prevent accidental updates, posts that match by title only are skipped. To update one, add a slug or post_id to the front matter (updates require Pro).
What if the Media Library already has an image with the same filename?
Pro asks for confirmation before importing. If you confirm, the existing image is replaced and its attachment ID is kept.
Can I undo an update?
Pro creates a backup before updating. Use History & rollback to restore the previous state.
Can I disable external-image attribution?
Yes. Pro settings control source captions and links. Attribution does not grant permission, so only import images you are allowed to use.

Holidays and closed periods

- “If a closing day is a holiday, open that day and close the next working day” handles rules like “closed Mondays, or the next weekday when Monday is a holiday”.
