The title explains it well, I think
The idea is as follows:
- Whenever a new item appears inside a Smart List (due to manual creation or modification - while outside this list; or date/time change), highlight this Smart List or mark it with some indicator.
- Inside the list, highlight/mark the items that have changed.
- Remove the highlight/indicators (from both the tasks and lists) after this list is selected and the items viewed (but only inside this list!)
What do you think? Is it worth to add such feature to the list to consider?
