So I play very aggressively, using an abundance of ships with Safety Overrides. Because of this, Peak Performance Time is continually something that I have to watch and manage. However, in larger conflicts, it becomes difficult to catch every single notification about PPT in the top left. it would be immensely useful to see an ally's remaining PPT using the tactical screen. maybe it could be done by showing whenever you target an ally (or maybe an enemy?) with the R key, in conjunction with the feature that lets you view from the perspective of other ships.
Regardless of how it's implemented, it would be an immensely useful feature to have.
