My opinion, for whatever it's worth, is that the Smalltalk libraries have gotten pretty chaotic, not the base libraries, but all the add-ons. It's hard to know and to find what's available. This is partially a matter of organization, but even more a matter of missing documentation and the lack of appropriate documentation tools, especially indexing and searching tools.
Further along these lines, there are real gems that need to see the light of day. For example, a number of packages included in BottomFeeder would be of great help to customers if they were better formalized and documented.
That leads to a question - what packages that in the goodies are people finding useful? What packages in BottomFeeder would be worth generalizing?
