I would like to suggest implementing options for the player to sort items by a selected feature.
Right now wands for example, seem to be grouped totally at random. Sometimes, one wishes to cast one wand after another consecutively and this randomity makes it a very tedious and annoying work.
Instead maybe we could have wands sorted alphabetically? When many wands of the same type are in PC's possesion, they could be sorted from most charges to least, with B/U/C status included.
That way 'z' command would be a much more streamlined way to use them and browsing inventory to drop unwanted wands would also be simplified.

The same applies to potions. Currently, many potions, even if they only differ in B/U/C status will be randomly distributed all over potion category.
Alphabetic order would be very nice here as well, with B/U/C status again taken into consideration as well as number of items in a stack.
Books are already sorted alphabetically from my experience, no?

Other groups of items that are usually abundant by mid-late game in PC's inventory are rings and scrolls, but virtually all item categories would benefit from this.
Missiles are kind of separate issue. It's critical to have arrows, quarrels, sling bullets, rocks and throwing weapons grouped separately and not mixed up like right now.
This would be archer's wet dream, but since ranged combat is so useful, all classes would benefit from this.

A very important thing would be to also add sorting to extended drop&pickup menus, since they are also commonly used, often at stores.
Personally I'm a pack rat - reading blessed scroll of ID, then sorting through 50k stones of equipment after clearing 2 greater vaults is no fun when I want to keep 5% of items of different types.
