Eclipse CDT: Change Annotation icons on that left bar D: ?

Hoi.

I love Eclipse. But i hate that huge square annotation on the le开发者_如何转开发ft, popping up every two seconds:

How can i change it? Been able to get rid of it, but I'd like something else than nothing.

(hate squares)

Right click on it -> General -> Editors -> Text Editors -> Annotations. Here you can configure which icons and where to show.
