Code review comment for lp:~stolowski/unity/expand-2nd-home-category

Can we at least do this when the search actually finishes and not arbitrarily after adding a few results?

Otherwise the category might get expanded, but as another lens finishes search and pushes more results it will again get unexpanded... Or is that what what we actually want?

That doesn't look right, we should be using HOME_VIEW in home lens (if that's not the case the id check should suffice)
