PharoLauncher

Smalltalk is launched by doing drag&drop an image file onto a virtualmachine file. This gets very tiresome and error prone when you have many image files for many reasons, like you might want to develop several projects in parallel or you might want to version your image than use version control system like monticello.

This app can launch, quit, delete images super fast. They are done by single click, or even faster, keyboard shortcut.
Although the name implies Pharo, one of the Smalltalk implementation, but it also works for other Squeak based Smalltalks as well. Squeak, Croquet, Cobalt, etc.
