It's not helpful for large inventories in the slightest, just instead of opening a trade offer window it will just get stuck for the same amount of time before sending a trade. The script you linked is outdated and unusable. I'm not going to waste time on implementing something useless like this. You can already change setting for trade to be sent automatically after opening trade window, and closing trade window after that, that's the best I can suggest. Of course you can also use the script you mentioned, at your own risk.
I would love to have the feature included that a trade can be sent without a window needs to open. This script (link below) here does it pretty well. Maybe you can check it if there is a change to also add that wonderful feature. Especially helpful for large inventories. Thank you
