You only just proved me right? Nice job? It was mentioned (and taken as a promise for some reason) that there would be improvements to make space more manageable. They have delivered on those mentions, but not in the form of actually increasing Vault Space - which there are a lot of technical limitations stopping this from happening. They added four new Kiosks since Rise of Iron that allow you to remove things from your Vault and have them stored in an artificial Vault.

Kiosks aren't improvement. They're glorified trash cans.
