Mind Maps are a great way to kick off a new project and Tasks are often a major part of this workflow. MindNode now offers native Tasks support. You can turn any child node into a task and check off completed tasks directly on the canvas. To help you stay on top of your tasks, MindNode will also show a task progress indicator on parent nodes that have children with tasks.
If you prefer Apple Reminders to manage your tasks, you can also export your Tasks to Reminders and MindNode will keep the completion state in sync with Reminders. For example when you mark a task as completed in Reminders, it will also be marked as completed in MindNode. This feature works across iOS and OS X.
Even better, if you use Reminders with 2Do, you'll be able to work on a project with a tree structure in MindNode, then share to Reminders and complete tasks either from 2Do or MindNode. Clever integration – though it would also be useful to import lists from Reminders and visualize them as mind maps in MindNode.
