2017 - iThoughts adds import to Mindmeister and SimpleMind

The new version of mind-mapping app iThoughts is now live. It features Siri integration, Drag/Drop and a new way of marking tasks as complete. There is also a feature called focus lock. With focus lock, you can now keep a bunch of topics in focus regardless of which one is selected. There is a new button in the top corner. If you drag/drop a topic onto it then the topic will be marked as 100% complete - great for check lists. Mindmeister (.mind) and SimpleMind (.smmx) mindmaps can now be imported. The Doodle feature now supports a resize option to resize selected parts of your doodle (see the +/- button in the toolbar.) Doodle also has better support for Apple Pencil.
