The ability to create custom favourites within the HD Guide is a feature that was removed with the latest firmware update. Overall, the client was streamlined to offer a better and quicker experience overall and the removal of custom favourites this was part of that process. Apologies if this is something you did make use of.
will they be re adding this feature in a future update?
Unfortunately I don't have an answer to that right now. That said you can file a feedback request with us and we'll forward it along to engineering for review. The details on that are here.
