This is a plugin related to doing batch actions related to tasks. In the near future, I'll aim to add batch moving and completing tasks to this plugin in the future, but for now it only tags.
Select the text of a task, click on "Extract Selection" and select the inline tag you want to tag the tasks. This will automatically add the note tags to all selected tasks.

List of features:
Tag tasks in batch: Add an inline tag to various tasks at once
Move tasks in batch: Move a group of tasks to another note
Delete tags in batch: Deletes an inline tag from various tasks at once
Edit task details in batch: Edits the task details of a group of tasks. The current supported task details are:
Hide Until
Duration
Priority/Urgency
Task Score
