Disambiguation Control by Jon Ingold Version 10/170416
"Allows finer control over the disambiguation process used by Inform to decide what the player was referring to. Less guesswork, more questions asking for more input. Also removes the multiple-object-rejection in favour of asking for more information."

"Exposes the Glk windows system so authors can completely control the creation and use of windows"
