Hey would be amazing if the addon had target of target for arena 1-3 this is amazing for healers as it allows you to see party member HP on the arena frames but also who is being targeted with burst a lot of healers are currently using gladius just got get this functionality and moving the settings to make it work on their Sarena. This would be a great include

If you are requesting this in order too see which party member needs heal, I think the existing module does a much better job:

it shows yellow aggro border when a party member is targeted by one enemy player, and red border if targeted by at least 2 players.

With the feature you request you need to check arena frames first then translate the target info to which raid frame you need to target and heal, and it's confusing when you have 2 teammates of the same class (very possible in solo shuffles)
