Short tip about a nice new functionality, just forgot to mention it yesterday, sorry:
You can now copy an action within the same level. The app will create a copy of the action you chose to copy, with the name prefixed with the "Copy of: " text.
"Within the same level" here means that if the action copied is under a goal, the new action will be created under the same goal. If the action copied is under another action, the new action will be created under that same action.
Data copied - action and all its sub-actions, names with details. No recurrence or reminders are copied. Hope you'll like the new feature :)
