I’ve got my mesh object and there are little pink origins everywhere. It’s like an origin convention exploded all over my project. Ick. Can I toggle the visibility of the origin dots on & off?
Thanks
You could turn axis on in draw extras. Then your origin convetion wouldn’t be so monotonous. 
To be serious, AFAIK there is no way.
But if you have that much objects you could move some to an invisible layer or join some to reduce the amount of origins. The joined meshes later can be separated again ([P] in edit mode).
