What gnome tiling window manager does Wenedell mention in the Livestream on X299 and Threadripper

Basically what the topic says, Wendel mentions a tiling window manager for Gnome in the livestream of Aug 26 about threadripper, fedora and x299. I think I heard him call it Tilux or Thailux or something, but searcher for either of these only turn up funny links about thai tiles manufacturers. So what Tiling window manager does Wendell talk about?
Cheers,

Tilix terminal

Thanks @gentooman I must have misheard. I thought he said window manager, but he said terminal emulator I guess. Cool. Checking it out nonetheless (even though I lover terminator quite a bit).
