We are constantly monitoring our Forums to see what our users lacking and try to add those items in future packs. If you have such an inquiry, please join the conversation with your ideas. It happens that sometimes one of our veteran users come to the rescue and provide the items you were looking for. Also if you have some artistic skills, you can add items on your own by using the Developer Program. If you happen to create something which you think would add value to other users, you can submit your creation and share it with others.
