This is a simple plugin that will monitor your notes for checklist items tagged with #todo and save them to a todo.txt file in the root of your Vault.

It also parses some of the Obsidian Tasks notation for due dates and priority to the todo.txt standard.

My use case is to receive notifications for my upcomning tasks on my phone. The way that works:

• I add a checlist item anywhere in Obsidian, give it a due date (Obsidian Tasks style) and a #todo tag.
• This plugin automatically creates and updates a todo.txt in the root of my vault.
• I sync that vault with my phone via Syncthing.
• I then point Todo.txt for Android or Simpletask to the todo.txt file.
• My phone sends me reminders of upcoming tasks.

Note that this is a one-way process. Changes in Obsidian will overwrite the todo.txt file, but changes to todo.txt will not be reflected in Obsidian.

This is a workflow that works for me, it might not work for you. Feel free to open an issue if you have any ideas or notice any bugs.
