Reinier,
Sorry for late response.
is this comparable to the SLL's from Visual Smalltalk? Are you using VW 3.0 yet? We denied the "offer" to upgrade.
I'm not familiar with either version of VS so I can't tell if the thing I want to do is similar to SLL's. I was 'born' in VisualAge. In VA 4.0 and newer, they have a similar concept of "image components" but I don't much like their design and would never suggest Squeak to do the same thing.
