Its not exactly what you were asking for, but Ive released recently a free internal cheat you can find in my profile, inside threads i guess.
Although i didnt pay special attention to what you mention specially, i do support the game in general which includes being able to draw on inventory and get object information like affix and the % of quality of the affix and many other things, you can also get all this information from the items in the floor, dont need to be in your bag.
The project offers large LUA API that im willing to improve if someone who is using it to code requests me.
Go take a look if you want, keep in mind tho that not much of this is explored by me, I just did a proof of concept to highlight items based on some filters, for more, someone else who play the game needs to work on it with the API I did.
Diablo is not very popular game but I though was sad to just discontinue it, so I decided to give it free for now, the project is in vital support tho, dont expect i work a lot besides keeping it updated.
