Yes! I like this and i want this! :-) I also want an option to show a trail for all party and guild members in the same color as their dot so i can steal their mining paths :-P
If you were grouped with the house druid, you'd get a detailed path leading to where every "adorable" was creature that she had spotted, as well as every bump or object she wanted to jump over. Her jump counter is in the thousands - on every character.
