I believe that the traditional SystemBrowser of Smalltalk of old has been made unusable by the amount of code (and structure) you find in today's Smalltalk images. So this is to show you an alternative, a different way to browse through packages / classes and methods and code. This is Spec-based. https://picasaweb.google.com/lh/photo/ic_fRnBXXdyqbiJ5NRP9YtMTjNZETYmyPJy0li... What is missing / targeted ? * Drag and drop reorganisation of the tree as preferred / or as package / category reuse. * A good search facility in the tree. It is already keyboard navigation friendly (since the tree view is). * Most / All menu methods of a complete System Browser. I'm planning on reusing the OmniBrowser command structure as much as possible (to make it faster). * Funny ideas on how to use the tree structure : group / selection display, queries, metrics ... ** There is probably a lot more to be done here, but it would probably require Mondrian or other graph visualisation tools. Expect the code sometime by the end of the week, in a Pharo 2.0 / Pharo 1.4 version.
