Terra is GTK+3.0 based terminal emulator with useful user interface, it also supports multiple terminals with splitting screen horizontally or vertically. New features will be added soon. It's very new and experimental project. I'ts written in python with python-gobject.
Terra is now able to be displayed on multi-screens at the same time. You will get independant windows by screen.
Features added based on upstream (https://code.launchpad.net/~ozcanesen/terra/trunk):
Use Terra Terminal on a multi-screen configuration
Use multiple Terra Terminals on one screen
Combine both configurations from above:
Open a new Terra Terminal
Set a predifined position for each App (Top/Center/Bottom/Free and Left/Center/Right/Free)
Start a specific program on each frame, saved in your layout.
Save Tab Names correctly for all Apps.
Features to come:
Save your layout configuration.
Start a graphical program instead of a term program.
