Code review comment for lp:~kamstrup/unity/home-lenses

1519 ~Lens();

I believe this should be virtual now.

1538 template<class RowAdaptor>
1539 Model<RowAdaptor>::Model()

The missing model.SetGetterFunction(...) could be a very nasty surprise in the future.

One of weird things I noticed is that when using keynav in the home view (specifically the down array) sometimes the "See xx more results" doesn't get highlighted and can't be expanded by pressing enter.
