I do see that there have been several ideas towards setting groups up for types of friend (such as those with icons, those with wood trees, etc.)
If the grouping is not possible, another idea is letting us add labels. or maybe color dots we could put next to their name. We could assign our own values, like a blue dot is herbs, yellow is wood, red is spice, black is idols. that way we could see what is on their street to visit them.
Just an idea, thanks much. <3
