Hi, I am one of the engineers working on MindNode. We don’t register MindNode as the owner of “md”, but as an app that can open and save to this file type. If we don’t do this we are unable to import and export Markdown files. You can change the default app anytime in Finder by using “Get Info (cmd+i)” and choose an app in the “Open with:” section of the Info window.
