This both of these are great addons (I use Itemization Browser religiously), I found it hard when doing trial or groups trying to find out who dropped what, if they needed it and so on. Hence, Wish List.
Wish List indexes all set items in the game, saves it, then lets you search for sets.
When you want to farm a specific item, you click on that set, choose which item type, slot and trait you want and accept.
The item gets added to your wish list, which you can browse and remove items whenever you want.
If you or someone in your group loots that item, you get notified in chat and on screen.
Simple as that =)
Curious to know your thoughts and please, do test it out and let me know what you think.
