Comment 2 for bug 754424

Attaching a mockup of a possible solution.

The idea is to let the first item in the sample apps be a place holder, that when clicked repopulates the list with all avail apps for the particular category sorted alphabetically.

The reason why we need to go about it like this is that there is currently no way in the communication between the lens/place daemons and Unity/Unities to signal that the expander has been clicked and that the data daemon should take some action (repopulating the section in this case).

So; the proposed solution can be done without breaking API or anything. It does require a non-trivial amount of code, but is doable if the release team looks very favourable on this :-)
