In Team chat when you donate cells, there is no way to see how many you have donated to a person. I try to spread out who I help. For Legendary cells, I try to give 1 or 2 cells per person. I go in and out of the chat a lot. New requests come in and filled ones go away. I can't tell if I have given to a person already. It would be nice to be able to see how many I have given.
Now in the grand scheme of things, I would rate the priority of this enhancement low, but still desirable.
