This applies both to model wrappers and GUI component wrappers, but one can certainly extend explorers to (e.g.,) jump to a nested visual component subclass.</div><div><br></div><div>The MVC framework extended all the way up to the top-level views, where it’s convenient to have separate views and controllers.</div><div><br></div><div>stp</div><div><div>

Load ‘ESqueak.release.1’ and make the UI thread run in a Vat.
Use eventual sending, not with math, but MVC component level.<br>
