Strikethrough / Hide completed tasks

[Dymium]

Not really, I can, for example, make a search to view all my open tasks or next actions.

But when I'm reviewing every (sub)project it would be nice to hide the completed tasks from the data explorer with a toggle (or hotkey) and only display these when I want to see them. Otherwise they only pollute the data-explorer tree.

I don't want to delete them completely because I also make notes in the completed actions on what is done with that action.

Don't know if this is difficult to implement? Maybe a conditional hide attribute?
