How about Load Applet? I think that is usefull to see the cpu and ram usage bar. Many times I look them to see if something is still loading so I do not hesitate on trying to get something to work if there is load still going on. And those help to see if something stays consuming resources in the back. And that applet has also the sceenshot as well as screen recording which could be usefull if someone wants to show something.
