Team Kill has released v1.3 of KillEd which adds a few new things, including support for Doom Legacy. As the page says, "I think I've gotten all the features, but if I didn't, I'll find them and add them. All that's missing is the AllTrigger line-def flag. I've also added a new INI toggle that lets the user decide whether or not the menus should display names for Kill items or not. The Doom Legacy feature is also controlled via INI file."
