[Pharo-project] Pharo Refactoring Tool

Hi, I'm a Masters student at Ryerson University (Dr.Dave Mason is my supervisor), and my thesis project is to significantly improve the refactoring capabilities of Pharo/Squeak. There was an interesting thread on this back on August 6th, but I would welcome anyone's input on what I should consider. My starting point is to bring Pharo up to the level of Eclipse (seehttp://help.eclipse.org/helios/index.jsp?topic=/org.eclipse.jdt.doc.user/con... ) but I would love to hear from experienced Smalltalkers about refactorings that are important to them. Thanks, Alia
