Hello Guys,
I came across an very handy addon that costs nothing, you can find it here
mobmap.de (also in englisch but the website is .de so you englisch speaking guys/girls don't type .com if you whant the englisch database just . de and you can choose )
Now a COPY PASTE text from the website.
The Addon
The MobMap Addon is an ingame database browser. It displays the positions of all known mobs and NPCs on the ingame map as well as the minimap. It also integrates itself into your questlog and finds the positions of quest mobs with just one click. And it does even more: it allows you to search the MobMap quest database, the merchant database and the recipe database.
