Hi Hans, Not available yet, but soon ;) I am hired by a company, Lam Research, to make that possible with Pharo. I just began to work on it, but IÂll announce it when IÂll have a first working version. Our goal being to be able to package and deploy easily desktop applications thanks to a tool that customize the deployed image. To avoid the right click on the World, a quick solution could be to open a full window in the world and define a right click here. Look openWorldWithSpec method.
