Last seen? [Suggestion]

I know in an FC, you can see how long it's been since a person was last online. Would that be a possibility for something on lodestone (At least, if they're over a certain level. That way, prevents someone from joining just to stalk someone else if possible.)? Trying to get cross-world groups together with friends that are only talked to on this game is a bit tricky, since not everyone uses Discord yet.

I've been thinking about the same. This would also be helpful for the purpose of the "Invite Friend to Return" list option. So you can see who is eligible for it or if they're close to the 90-day cutoff point we can even prod them one last time... or buy a time card for them as a gift.
