When a user assigns an icon to a tag in the inbox, it pulls from the "emoji" gallery. Front currently allows a user to upload custom "emojis," but apparently does not have capability for those uploaded images (emojis) to be assigned to a tag even though they show up in the gallery where the user chooses the icon for the tag. This would be helpful for teams that want to have custom tags with unique icons.
Same thing for views. It would be helpful (and fun!) to be able to add custom emojis to both tags and views to be able to help teams visually differentiate between them when using these features a lot.
