Beeps/Warnings on Expiring Nodes

For those that like to drop and run, some beeps or warnings or perhaps just a notification window to the side of the map can show all the nodes and their expiry time.. so that when some are < 10 minutes, we make sure we stop and go dig it up or sometimes we forget about a node.

a list of top 5 expiring claims with a timer on the map? in one of the corners ?
