    GTD Sync

    GTD Sync

    The Freeplane add-on that syncs a GTD mind map with a todo.txt file

    The Freeplane add-on "GTD Sync" enables you to use the non-linear representation of Freeplane to organise and review your projects, next actions and delegated actions. You can then use a todo.txt list manager like Simpletask for Android to decide on the go what to do in a certain context and to check off completed tasks The add-on imports new next or delegated actions and changes to existing next or delegated actions from the todo.txt file into the GTD mind map and then exports all next actions to the todo.txt file. In this way both files will stay synchronised. In addition you need a cloud service like Dropbox to keep your todo.txt file in sync between systems. For more information on Freeplane, see http://www.freeplane.org/wiki/index.php/Main_Page The todo.txt format is a simple set of rules that makes todo.txt both human and machine-readable, see http://todotxt.com/. The add-on is inspired by Freeplane|GTD, see http://auxilus.com/blog/freeplanegtd/
