A script you can bind to a hotkey that toggles the Hamster Time Tracker window

superH

#!/bin/bash
# @File Switch between current window and Hamster Time Tracker

# get current window
hamster="Time Tracker"
currentWindow=$(xprop -id $(xprop -root 32x '\t$0' _NET_ACTIVE_WINDOW | cut -f 2) _NET_WM_NAME|cut -d'"' -f2)
if [ "${currentWindow}" != "$hamster" ]
  # write the title of the current window to a file and switch to hamster
  then echo "${currentWindow}" > /tmp/hamster.dat && wmctrl -Fa "$hamster"
  # read window temp file and switch to it
  else lastWindow=`cat /tmp/hamster.dat` && wmctrl -Fa "$lastWindow"
fi

👍 thanks!
