I’ve put in a feature request (for both Mac and iOS):
Sort by oldest creation date in context and perspective views (oldest on top).
I know it’s possible to sort by Added, but then the oldest tasks get put at the bottom of the view. Working through my lists top to bottom I would then never complete my oldest tasks unless I complete the entire list.
For anyone else interest in this feature, please make a feature request to: support@omnigroup.com
