I sometimes have trouble coordinating with my friends on magma because I never have an idea of when they were last on. I strongly believe that a feature to tell when the user that you are following or is followed by was last on would be really helpful. I also believe that along with the “last on” feature, it should have a feature to this where you block people (ex. Stalkers, griefers, etc.) that you don’t want knowing when you were last on.
