The Pro edition will handle "subdatabases" (forms, tables, im/export TSV/CSV etc.), e.g. to store addresses, bibliographic data etc. and will also be able to handle metadata (maybe not in the initial release but soon afterwards). In addition we want to add a plugin architecture to version 2.0 to im/export data.
Thanks for sharing that information, sounds good to me. I am also looking forward to Applescript support which should ease the crosstalk with other apps (in this case databases). Can’t wait to get my fingers on it, too bad it has been delayed. You might want to think about an open or closed beta which at least breaks some limits of the personal edition. At least I would hereby like to apply for a possible beta program ;)
