• taskall plugin: A plugin that shows all windows(tasks) on a menu. You click the menu item to switch to a window. XFCE & Gnome 2.x also has this kind of plugin.
• When lxpanel taskbar display the title bar of terminal(xterm, rxvt, gnome-terminal) like user@hostname:~/aaa/bbb/ccc.  When the title has to be truncated, it will be displayed as ...name:~/aaa/bbb/ccc. It is very useful to help selecting the right terminal. To set the correct tile bar in terminal+bash. Please add below to your ~/.bashrc. By default Ubuntu 12.04 has it in your ~/.bashrc

  ~/.bashrc display current directory title bar

  # If this is an xterm set the title to user@host:dir case "$TERM" in xterm*|rxvt*) PS1="\[\e]0;${debian_chroot:+($debian_chroot)}\u@\h: \w\a\]$PS1" ;; *) ;; esac

to compile it

sudo apt-get install intltool
sudo apt-get install libmenu-cache1-dev
sudo apt-get install libiw-dev
tar xvfJ lxpanel-0.5.8_taskall.tar.xz
cd lxpanel-0.5.8_taskall
./configure --prefix=/usr
make

New feature:

Press right button on the taskall icon to open a terminal & execute 'top'  to display all processes.

Update:

Click left button on cpu plugin to invoke 'top'.

A bug，background &  was missing 

This will cause the freeze of lxpanel。Source & executable of the first article has been updated.

void exec_top()

{
if (system(
"sh -c 'for i in lxterm rxvt-unicode xterm rxvt gnome-terminal konsole;do type $i>/dev/null;"
"if [ $? -eq 0 ];then $i -e top; exit;fi;done' &")) {
printf("failed\n");
}
}

sudo cp cpu.so /usr/lib/lxpanel/plugins

Now invoke lxtask if available,  otherwise use 'top' instead.
