I have installed the plugin and kept the default value of “## Completed” as the area to place completed tasks. When I complete a task that is listed elsewhere in the note and then click the hotkey, it tells me there are no tasks to move.
Just tried this plugin out as well. Apparently it only works in edit mode and is still very inconsistent on behavior. I get varying results if I check an item complete. Usually works correctly if i use sidebar button. But if I use hotkey it will either move to ## Completed as a completed task, Uncompleted task (unchecked) or just uncheck task and leave in ## Task? At this point I find it not very dependable. Going to the GitHub page shows it was last updated 10 months ago so not too encouraged that this will be refind to a usable plugin.
