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 :-)
