I'd like to see some sort of display cases introduced for the "trophies" we bring back from jobs. A simple way of organizing or displaying our prized collections without them banging around or lagging through things. For example, a mask could be placed on bust, or a sword on a sword stand. A knife could be displayed behind glass as part of a set, or we could have a bucket in the corner that overflows with cash depending on how much was deposited inside it. As for other items, perhaps a locker that could double as an inventory screen for storing any undisplayed items so that the office isn't cluttered with dogtags, boomboxes, and other fun junk.

Even if we were only given a set number of display cases & mannequins to freely arrange, or even have assigned ones that were unlocked once the corresponding item is brought back would be amazing. We could even have full sets that are spread out over multiple levels as hidden pieces. Clean a level once and find a hidden samurai outfit piece. clean the level again and come across a knight's chest armor piece. This would encourage players to clean levels in hopes of completing a full outfit to display, or possibly even wear once unlocked. This could have multiple different outfits from scary to funny to downright outrageous. Possibly even mix & match outfit pieces for more hilarious costumes. A gorilla knight or a clown samurai.
