#you will need zenity installed for this

#select a raio button and press ok
#click on a window to kill, stop or resume
#option 4 - task list, will bring up a list of all your owned tasks (this could easily be modified to show all tasks)
#you can then select one or more tasks and again kill, stop or resume them
#this probably needs to have a propper gui made for it but zenity is ok for a couple of small dialogs

#i made a simple  launcher for this and put it in my top bar so all i have to do is click on it
 
#change this to select an icon for the windows
