I used this for a while to put twitter back the way I wanted it. Someday I might use this again, who knows.

TwitterFixer.user.js

window.addEventListener("load",function(e){
	var dashboard = document.getElementsByClassName('dashboard')[0];
	dashboard.style.float="right";	
	
	//document.getElementsByClassName('js-recommended-followers')[0].innerHTML="";
	document.getElementsByClassName('trends')[0].innerHTML="";
},false)
