I like how it is but wish some things were limited by the node grade. I hate it when gathering at a lvl 3 node and I get moko grass or cotton balls more than what I am actually after.

I wouldn't want a list per se but rather some way of targeting a specific item or lower the number of possible item types per node.
Ie....this node you sense lavender, midland Basil, and popotos can be obtained here.

Like a new ability in line with arbor call.
