Matthew made some enhancements to ToolBuilder, which currently held in
separate repository at
squeaksource.com/DeltaStreams under the ToolBuilder-Kernel cat.

Some of the changes would be really nice to integrate in trunk, like

- renamed PluggableListSpec>>size to listSize
- added PluggableListSpec>>listItem, as an optimization to only fetch
items in view rather than the whole list, when scrolling

or maybe i'm not aware, and they are already in trunk?
I just want to ask anyone who is interested to make an overview of
changes and decide if its safe to push them to trunk image (or
official ToolBuilder repository).
