I am looking at this configuration and had fun loading the Batcave thing. What is this green area and slider on the right for? Found fixIssue5656 "Issue 5656: Large fonts make tools slow http://code.google.com/p/pharo/issues/detail?id=5656" | smallerFont | smallerFont := LogicalFont familyName: 'Bitmap DejaVu Sans' pointSize: 12. StandardFonts defaultFont: smallerFont. Which I didn't knew about and for sure will help me! All the loginTo things are quite useful as I faced this kind of situation enough to care :-) Would be great to have a logout, in order to give images to other people without leaving credentials around. This pref also useful: customizeCompletion NECPreferences enabled: true; caseSensitive: true; expandPrefixes: true; useEnterToAccept: false; smartCharacters: true; smartCharactersWithDoubleSpace: '[]{}'; spaceAfterCompletion: false; popupAutomaticDelay: 100. And a lot of other things that make it clear that a simple prefs file is not enough in your case :-) Phil
