Please add global weight multipliers to items for different dimensions so that all items can be heavier or lighter depending on what dimension the player is in. I feel that this will not just be good for the vanilla game but would also help with modded dimensions (for instance galacticraft, aether, dimensional world, RFTools etc). I feel that this is something this mod is missing and would introduce a new dynamic. Keep up the good work =D

@AlastairBooth can be already achieved through Potion Effects.
(Increasing the max weight based on which potion effect you have active and you could just make a potion effect that gets added when entering a dimension)
Though the idea is interesting.
