you mean to know what traits your guildmates know? and they must also use this addon to give you this info?
looks like there is no uch addons anymore
i agreed it might me usefull, especially it was usefull at the start of the gme when there is not alot crafters
but today you can buy any trait white item for reearch at the guild trader like for 100-500g, and IMO its not a big deal if you need few items for research
about sets
- Crafting Station give you a tooltip and mark on the map
- WaypointIt(not released yet) will give you a quick way to set waypoint with nice arrow to guide you to the point
