FS#9515 - customisable quickscreen. Allows you to choose which setting you want displayed on the quickscreen.

Allows almost every available setting. (change the options in settings > general settings > quickscreen items)
Not every setting will work perfectly, some might need aditional handling if the change doesnt take effect straight away (let us know which are problematic so they can be fixed)
