Those are good suggestions
I’m just starting on messing with the actual inventory code so I should be able to easily get a function made to list all of the items, sorta like a grocery list: battery x 500, shovel x 1, thread x … you get the idea; containers would be listed in here too so you know what options you have for containing things outside of the normal inventory view. I want to have it be tabbed like the crafting screen [& key] with a ‘list’ and ‘inventory’ tab.
The actual inventory view will probably look a little bit like this:
Containers in the inventory will be pulled from the list of worn items and displayed.
a - backpack [0/40]
b - messenger bag [3/20] [v]
| a - meth [30]
| b - aspirin [100]
c - mil. rucksack [xx/80] [v]
| a - backpack [0/40]
| b - backpack [5/40] [>]
…and so on. the [>] denoting it has something inside it but not displayed, [v] is displaying the items. I might limit it to only one container open at a time so that the screen doesn’t get filled up with stuff too much. As you can see, each of the containers has a letter, and the contents are lettered relative to the container itself. I’ll likely make it so that you press the key for the container, then a direction keys to open/close. Might make it direction key based entirely, similar to the construction menu (* key). I haven’t really figured that out though 
I like the idea to display moves used to interact with items a lot. Not sure about the last suggestion, but I will give it some hard thought 
All of this is still subject to wild changes though, so don’t take this as a finalized format.
Edit: derped about the named of the crafting screen [& key]
