Display a ground circle around the player

[Aznox]

I don't know if an existing Add-on has that ability (search returned nothing)
I am not even sure the game's API provides the needed feature set, and doing it by other means could be against the ToS.

The need would be to display a circle on the ground (like any AoE effect) centered around the player.

Mandatory features would be :
- ability to select the radius of the circle (to match the range of important PBAoE skills)

Nice to have features would be :
- ability to configure circle color and brightness
- ability to configure multiple circles
- ability to activate circle based on conditions (in combat, duration after event, etc..)
- ability to configure other shapes than circle, and to offset them (ex: rectangle in front of you)

Curious to get your thoughts about this.
