I'd also prefer it if the DeDRM plugin only did its thing on import. However, this is only an issue if you didn't have the plugin or it wasn't working when you first imported a book. And it's only really an issue if it still can't be read or converted. In other words, if the DRM can't be unlocked when trying to read or convert. If you really need to check an original file, disable DeDRM and then try opening it with calibre's ebook viewer. Then you can re-enable DeDRM and re-import the book if needed.
