The process manager tells me which window/process is hogging memory. But I have multiple windows open on multiple workspaces. How do I switch to that window so that I can see what it is and decide what to do about it? Until recently, clicking on a window listed in the process manager would bring that window to the current workspace (ubuntu/xfce). That changed recently. Now clicking/double-clicking does nothing and there only seems to be the option to kill the process. I guess I can kill it and then look at recently closed windows to see what it was. But that is a bodgy. Can I fix the process manager so that when I click on one of its listed windows, I get taken to that window on the workspace where it resides? (It always was inconvenient when previously, double-clicking on the window in the list, brought that window to the current workspace. You had then to work out where it had come from if you wanted to put it back). Firefox's window/workspace management is otherwise excellent. It's the best in my opinion. When it starts-up, for example, it puts all the windows back on the workspaces where they were when it was last closed. Very nice.
