I like how you can already equip weapons and armor your character is holding through the companion, but I'd also like access to withdraw and deposit items from the vault to my characters through the companion. I feel like it would make things easier when switching between characters, instead of needing to go back and forth to the Tower. A bank system to store glimmer and possibly Crucible/Vanguard marks would be a nice feature, specifically for glimmer because I sometimes reach the cap and continue to do activities without even noticing, meaning I'm losing out on some valuable income. Possibly just add it to the vault? Loving the game thus far, Bungie. Hope this is considered. Praise the sun.
