Pretty sure you ranted about this one already a number of months ago as well.

I generally agree though, some games do tend to handle it weirdly, where either the quest items take up arbitrary space in the main inventory menu and/or there's a risk of accidentally selling them.

Similarly, I'm not always a fan of things like crafting materials being dumped into a main inventory section either. Unless they can also be used as repair tools for equipment, they're not something you're usually going to need to interact with until you're actively crafting stuff. (Survival games may be an exception here however)
