Terminix is a tiling terminal emulator which uses the VTE GTK+ 3 widget with the following features:

-Layout terminals in any fashion by splitting them horizontally or vertically
-Terminals can be re-arranged using drag and drop both within and between windows
-Terminals can be detached into a new window via drag and drop
-Input can be synchronized between terminals so commands typed in one terminal are replicated to the others
-The grouping of terminals can be saved and loaded from disk
-Terminals support custom titles
-Color schemes are stored in files and custom color schemes can be created by simply creating a new file
-Transparent background
-Background images
-Automatic (triggered) profile switches based on hostname and directory
-Supports notifications when processes are completed out of view. Requires the Fedora notification patches for VTE
