No, you summed it up pretty nicely.

I think the problem is you're not getting the right model of what you see
when you first look at the package loader. Watch the label "SM Package
Loader". Where does it tell you that you're seeing a subset of the packages?
Is there any way for me to see all the packages or search for one? Not on
the screen. So the user is left with the impression that "this is SqueakMap"
which is the wrong model.
An alternative to showing all packages would be to somehow clearly indicate
that you're seeing a subset of the packages. For example, name the package
loader differently, rather than "SM Package Loader" make it "Ready to
Install Packages for X.Y" and add a visible "Show all packages" buttons (the
context menu is not visible enough).

The classical problem of user interface design. At all times you have too
much information and too few pixels ;-) It's always a tradeoff. In this
particular case I think it's important to distinguish between "the contents
of SqueakMap" (the list elements) and "our view of SqueakMap" (identified by
what packages we can easily install, which ones we already have etc).

It could work. As with all things in UI design you need to try it on real
users. Fortunately you got plenty around here ;-)
