Sometimes a person(s), who was mentioned in a message (discussion), reacts to the same message.
I think, that reactions of mentioned peolple and other (not mentioned) in the message people are a bit different. Reaction of mentioned people may have additional meaning. Say, if someone posts a message, like “this person said, that …”, and mentiones this very person, then if the mentioned person reacts with thumbs up, it means he agrees/verifies/confirms the message.
Another example, why reactions may be differentiated (and may appear differently in UI), may be if owner of the project reacts to the message.
With this feature, it would be easier to not miss important messages while looking through discussions, aspecially long ones.
Enhance message reactions, so they can be given additional meaning and can be displayed differently in UI.
