Never was a fan of Manga inspired oversized weapons worn on the back compulsively. And though I love Larian, I HATE how they manage inventory and how they overemphasize loot. This extends to the graphical feedback or lack thereof. For instance, BACKPACKS should be a requirement to carry much at all and be shown on the character's back. Only large weapons, with the exception of polearms, should be worn (alongside backpack) on the back in my opinion.
A toggle for helmet on/off would be nice, but I would hope that this would cost a bonus action to toggle during combat. Suffer for your beauty
