I've seen quite recently more people not realising something purchased from the crown store under the "collections" tab is unlocked account wide. it would be nice if each relevant item had a little note along the lines of: "This item will be available to all of the characters you create on this account via the collections menu".

Sorry if this is already written on the crown store just i know when i made my first purchase of a horse when i had just started i had no idea for a long time my other character also had access to the horse, or how to access it, so if it is mentioned somewhere it certainly isn't somewhere obvious. It might even increase sales if people realise that when they buy that mount all the characters can use it
