Hi there! Thanks so much for your suggestion. While we do not have a feature to move between InDesign and BookWright/Bookify/BookSmart, we do have a feature that will allow you to import from BookSmart and Bookify into BookWright. In case this is something you are interested in, we have a help center article located here: https://support.blurb.com/hc/en-us/articles/207792556-Import-book-files-from-BookSmart-into-BookWright.
