Tilix (aka Terminix) is an interesting terminal emulator based on GTK3 like so many other alternatives that we have in GNU / Linux. You can learn more about the project or get hold of it from this web site. In addition to having maximum flexibility and power for advanced users who need it, the emulator has interesting features and concepts that will surprise you. It sure is a better alternative than the default terminal emulator that is included in GNOME environments, and derived from it.
One of the peculiarities of which I speak is that it is a terminal emulator mosaic type (or tiling), that is, the windows do not overlap, but are housed in the screen in the form of a mosaic or flooring, fitting into the holes in the screen, so we will have everything at first glance without minimizing or maximizing windows when we have several of them simultaneously. We already talked in this blog about tmux, the multiplexer terminal windows that could help us to have several console windows to be able to work from several points simultaneously. Well, Tilix does something similar to tmux, only that it is a complete terminal emulator and not just a multiplexer for other terminals like the second one. In addition, its interface is simple and will not present too much difficulty, and the ability to have multiple sessions open.
In preferences menu We can modify many aspect parameters, such as color, and size, etc. You should also know that it allows you to have several open panels, with multiple sessions as I have said, ability to anchor or remove terminal panels, support for profiles, a very good support for keyboard shortcuts, a drop-down mode (Quake), customization of colors for the schemes and themes for the appearance, different options for the window styles, and a friendly and intuitive interface.
