Knowa allows you to star any message in a discussion.
This is useful for saving important messages and information for future viewing. Or can be used to create a list of reminders for messages to follow up with at a future time.
Starring a message is easy. Simply click the start icon on the top right corner of the message and it will immediately be highlighted yellow.
Accessing a list of your starred messages is done by clicking the Star ⭐icon in the sidebar (or top bar on iPad and mobile).
