Dendron has the functionality in the configs to work together with the Todo Tree, and it adds a new YML key

TODO: title

intoa. task note. but when I complete a task using

Dendron: Complete Task

it doesn't update the

TODO: title

part. My suggestion would be that it should update this one as well, or even do it automatically when the status changes, just like how

updated

is automatically changed on each update.
