Remove Function from 'Post To Timeline'

So I was looking around and tried to find out where I can remove a function from the 'Post to Timeline'. For example: I do not want the 'Share a Link' there, so how can I remove it?

I am hoping that I will not have to hackup the core files for this.. but so far that's what I am thinking will have to happen.

Good idea, should be added to settings in the "Timeline" module.

Be nice to select what members are able to post to their timeline.

Check modules/boonex/wall/classes/BxWallModule.php

 Yeah I saw that.. Actually there are a few locations in that file for sharing a link..
