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.

Over the years, the developers behind Linux have made great leaps in order to provide better services and functionality to their loyal users. Before, personal computers that have Linux operating system were deemed to be unusable. But now, a lot of people are starting to become more enthusiastic in giving it a chance because of its improved usability.

But of course, not every technophile is born the same. In addition, you cannot really expect that every Linux desktop that comes out of the box has the same features. If you are quite new to this operating system, it might take you a long time before you finally learn its ins and outs. So to help you out, here are several ways on how you can make your computer more efficient and user-friendly.

1. Familiarize yourself with the keyboard shortcuts

Similar to Windows or Mac computers, devices that run on Linux have several handy keyboard shortcuts that can definitely make your user experience better. Commonly, shortcuts are used for creating word documents, but there are some great ones that are specially designed for the system. To make it easier for you, just long press the Super key, or the Ubuntu’s equivalent of the Windows key. After a few seconds, a list of all the keyboard shortcuts will appear. This will help you become more familiarized with each shortcut.

2. Use the pager

No, this is not the kind of pager that was used by your grandparents before smartphones were invented. A Linux pager is a handy tool that provides multiple workspaces for better organization of your files. Thanks to this feature, you do not have to waste your time in searching for your different virtual working tools.

3. Use drawers

These are slide-out menus for organizing any type of icon and applet that can be found on your screen. If you like to add a lot of shortcuts on your home screen, you can use these drawers to prevent your desktop from becoming too cluttered. You can create several drawers for your social apps, games, most commonly used work tools, and a whole lot more.

4. Package manager

Linux devices usually come with a built-in package management system. The more modern versions of this system are fashioned just like an app store. The Ubuntu Software Center and Synaptic, for instance, features a variety of apps that you can download. That way, you don’t have to open your browser just to search for a program.
