The next-gen version of MindNode has significant differences in its file storage and management functionality. Originally, Mindnode documents were exposed in the file system and stored in iCloud. While the new version still uses iCloud, documents are technically stored in a database and not directly accessible by the end user. MindNode Next allows you to copy links to specific documents from within its integrated file manager, but those links are “MindNode.com” links. I can’t speak to whether they’re exposable through AppleScript.
