 > Blender addon for picking rig contollers
 
 Rig_picker is an OpenGl tool for having a 2d interface for the 3d animators allowing them to pick a controller easily.
+The addon is drawing 2d shapes inside a dedicated Node Editor Area using the gpu module.
+You can use multiple pickers for one rig, each picker shapes are in there own collection.
