The terminal emulator with a lot extra...

Extraterm is an open source project to build a modern terminal emulator with radical new features to make it more than just a dumb viewer for text output. The aim is to drag the terminal emulator kicking and screaming out of the 80s and into modern computing. More background information is in the Why document.
The primary developer is Simon Edwards.

:warning: Although generally stable, Extraterm is in development and alpha/beta in quality. Use at your own risk. :warning:
With that out of the way, the primary author does use it as their main terminal emulator on a daily basis. The basics are in place and it will run most common terminal applications such as vi, emacs and joe without problems and even more demanding applications such as midnight commander.
