Create emojis that can be used on the Apple platform. There are so many Harry Potter fans out there this would be a big hit!! 
Make the emojis more accessible. This could be done with an app update or an Apple update. Consideration should be given to all movies 

Suggestions would be things like Wands brooms spells snitch just themed Harry Potter items that include all of the houses as well. Characters and all gif wouldn’t hurt either!!
