Inventory sorting is an annoying but universal chore for any resident who wants to stay organized. When thinking about how I avoid the same issues in other file management systems, one of the biggest boons to keeping on top of data organization is being able to choose the location an incoming item is saved to.
Imagine that, when an unpacker HUD sent you a folder, instead of simply hitting "accept", you had a new menu that let you select which folder it unpacked to. Right now, all new folders simply go into "Inventory", but what if you could tell it to put that folder into "Objects->Home->Furniture and Decor->Chairs and Sofas"? Your item would immediately be sorted directly into the place it belongs so you could find it later. You could then have that folder appear in a "recent places" list for easy access the next time you needed to unpack a similar item. Maybe you could also pin favorite folders, for instance "Body Parts->Cosmetics" could be pinned if you know you buy a lot of makeup layers and unpack to that location often. This could also be used to help creators keep their items more organized when working on new projects, as the same menu could be used for bulk, material, and mesh uploads. Being able to see "recent folders" and select your project folder would help immensely with keeping product related files together.
This should be an option that could be toggled, either in the "accept/decline" or upload menu, or in inventory settings. Some people won't want to be pestered each time they acquire something new, but I know it would certainly help me, and many others as a major quality of life improvement.
