Comment 3 for bug 798197

Hi andreselsuave, here is a brief outline of how I built the applet with this patch applied:

sudo apt-get install build-essential fakeroot dpkg-dev
sudo apt-get build-dep window-picker-applet
mkdir tmp
cd tmp
apt-get source window-picker-applet
cd window-picker-applet-*
wget https://bugs.launchpad.net/ubuntu/+source/window-picker-applet/+bug/798197/+attachment/2171550/+files/show-windows-requring-attention-on-all-workspaces.patch
patch -p1 < show-windows-requring-attention-on-all-workspaces.patch
dpkg-buildpackage -rfakeroot -b
cd ..
sudo dpkg -i window-picker-applet_*.deb
killall gnome-panel
