There is a way to see all hidden items on a node but you have to have gotten 3 'hits' of HQ (Chain 2 of HQ on the tooltip). On nodes 10 levels and under Unearth3/Leafturn3 will make each 'gather' HQ, and then use Luck of the Pioneer. Not always super helpful if you are wanting things like birch logs or something of that nature in HW onwards, but it is a bit helpful when looking for maps or those seeds you can only get 1 of anyway.

ARR nodes are the worst, with the items you can only get 1 of (seeds and soils being the main ones), plus the timed nodes are every hour, unlike HW onward where they are every half hour. I wish they'd go back and redo the ARR nodes.
