Yeah, the carousel is not taking categories into account
currently. Should be relatively straightforward to add though, see
below.

[..]

There is a new sortmode to the AppStore(s) (both the gtk2 and gtk3
version) so hopefully its just ensuring that the category AppStore is
called with sortmode=SortMethods.BY_TOP_RATED for the per-category
top-rated. This should also work with searches (if we wanted to sort
by top rating). I have not actually tried this yet and I'm not sure
about the performance of it.

Cheers,
 Michael
