Would like a mod that starts the player with only their hotbar & 2x2 crafting grid. Inventory slots open with various different ways, either by time played, stages, achievements, crafting a bag/sack, etc. The more customizable, the better.
I want it to be more customizable than that. I want it to have multiple options to open the slots other than just "completing achievements or via certain items." If I want to set it up so they can gain inventory slots for every X real time played, I want to be able to. Or have it so X number of slots open when you kill Y number of hostile mobs. I want it to be fully customizable.
