Very clever to advertise for your titlepack
I would prefer that the players are able to decide it on their own. If players are able to customize their interface, you'll satisfy more people compared to if you would restrict the possibilites on only one option (e.g. top left, bottom right etc). Everyone has a different preference/taste (for example: Somebody likes to have as much information as possible in the UI, whereas somebody else likes a rather clear and simple UI)
My opinion: The more a player is able to customize their UI, the more people you'll satisfy.
