Qterminal is a Qt-based multitab terminal forked from QTermWidget, it is lightweight, open-source, specially designed for LXQt desktop environment. Author of QTermWidget had no time to make it more advanced, thus this fork was created. Unlike Tmux or Screen, it is much easier to deal with it.
"Initially this project was started as an attempt to create relatively light and stable terminal emulator application like Konsole or gnome-terminal but without any dependency from such monsters as KDE or Gnome. The author was looking for such kind of application for a long time but haven't found anything worth while."
It offers features like vertical and horizontal terminal split, zoom in or out, terminal tabs switcher, background color scheme adjustments (choose from predefined schemes) or change background image, font resizing, shortcut keys, hide/show scroll bars and windows borders, and many more from preferences.
Using Multiplexer features you can create as much multi-screens in one terminal window as you want, you can kill the current window, copy text between windows, scroll with in split window using mouse, easily switch between windows, etc. All windows run their programs completely independent of each other. Professional may find it useful and very handy with a lot of features.
