GNU Screen

Now I'v found a complement to my favourite window manager - Evilwm + GNU Screen.
Screen is a full-screen window manager that multiplexes a physical terminal between several processes, typically interactive shells. Each virtual terminal provides the functions of the DEC VT100 terminal and, in addition, several control functions from the ANSI X3.64 (ISO 6429) and ISO 2022 standards (e.g., insert/delete line and support for multiple character sets). There is a scrollback history buffer for each virtual terminal and a copy-and-paste mechanism that allows the user to move text regions between windows. When screen is called, it creates a single window with a shell in it (or the specified command) and then gets out of your way so that you can use the program as you normally would. Then, at any time, you can create new (full-screen) windows with other programs in them (including more shells), kill the current window, view a list of the active windows, turn output logging on and off, copy text between windows, view the scrollback history, switch between windows, etc. All windows run their programs completely independent of each other. Programs continue to run when their window is currently not visible and even when the whole screen session is detached from the users terminal. - [url=http://www.gnu.org/software/screen/screen.html] GNU Screen[/url]
Previously, I used to open a lot of terminal for the shell command, system monitor, chatting, playing mp3/video etc. Using screen, I would minimize the number of terminal by running screen inside my terminal and let it manages all the console windows. Using screen is as simple as a few keystrokes - ctrl a c (new window), ctrl a n (cycle window), ctrl a W (window list) etc. The true power of Screen is its ability to [i]detach[/i] and [i]reattach[/i] from the terminal. 'Detaching' let the shell running at the background while 'reattaching' let you continue from where you'd left it out, given a session ability. To add some fancy thing to Screen, we can have status bar that display the list of windows, current time/date, hostname etc- mimicking the Windows taskbar. Thanks to root@ittutor.net for the tips.
