As it says the welcome workspace of Pharo, you can install O2 like this:

Gofer new
��� ��� squeaksource: 'MetacelloRepository';
��� ��� package:'ConfigurationOfO2';
��� load.
���
��� �((Smalltalk at: #ConfigurationOfO2) project version: '1.2') load: 'Dev'.



That will install the O2 browser.You will notice this is a different browser. There are narrows pointing to left and right that may be something similar to what you want.

Anyway, did you try WorkingSet ? Read this link:

Hi alex

Some browsers like the O2 browser supported it but it is a bit ad-hoc and slow. You can try by loading
ConfigurationOfO2 from the MetacelloRepository repository.
