Description:
It would be very useful to have a card search functionality directly within Trello’s main notification panel.

Currently, when users receive multiple notifications, it can be difficult to quickly find notifications related to a specific card. Adding a search field to the notification panel would allow users to search by card name, card ID, or keywords and quickly locate the relevant notification.

Suggested functionality:

Add a search bar at the top of the main notification panel.

Allow users to search notifications by card name/title.

Display matching notifications/cards as the user types.

Keep the existing notification functionality unchanged.

Use case:
For users managing multiple boards and cards, this would make it much easier to find a specific card-related notification without manually scrolling through a long list of notifications.

Expected benefit:
Faster navigation, improved notification management, and a better overall user experience for users handling large numbers of cards and notifications.
