Filfre
From IFWiki
A Z-machine implementation for Microsoft Windows that integrates the scrollback screen along with the main game screen, thereby enabling users to perform copy/paste as well as text searches all in the same window. It also allows players to display their current inventory, the verbs being used and the object tree by clicking on the appropriate menu options.
Filfre was created and is maintained by Jimmy Maher. It is currently at version 0.94 (as of July 21, 2006). The name comes from one of the Infocom spells.
