Spark is not showing (0 online) near group’s name if that group was initially empty upon login. If someone goes online when (1 online) is appended. But if that users goes back offline it shows (0 online). I think this is not necessary and breaks design, when all initially empty groups are not showing that state. This should be shown all the time or never (option in preferences could be). though i prefer not to show (0 online) at all, cause i think this is useless. Anyway, should be the same behaviour for all groups.
