An SDML launcher is now provided, with facilities to manipulate users and models. Logging in and out, and changing password facilites have been moved from the SectorModelBrowser to here. Models can now be created, removed, and filed in/out using the launcher, so that users no longer have to resort to Smalltalk. Menu options are added (to save images, garbage collect etc.) to the launcher and SectorModelBrowser to make the Smalltalk launcher obsolete. Each model automatically has an associated project; 'enter model' and 'exit model' menu options enter and exit projects. Models now have authors and can be given comments. All browsers on knowledge bases or group information (except those on retrieval and compilation methods) have their labels updated by renaming and are disposed of when they become obsolete.
