Ciao, i work with Pharo 4.0 and with the relative System Browser. My goal is to define a group where i add all definition: Package ( CMD n-e-p ) Class ( CMD n-e-c ) Protocol ( CMD n--e-t ????? ) Method ( CMD n-e-m ) relative to a specific problematic ( when i development - management it ). Into Pharo 4.0 this command works with some problem ( they do not always work as you expect ) I do some test with the Pharo 6.1 and seems that the group handle only the Package reference add. Anyone can give me directions about it? How i can 'group' some reference ( Package - Class - Method ) into the System Browser to have control to all the method relative a specific problematic ? I forget something? Thanks, Dario
