Why can't this just be done from the log? Is it that difficult? Forgive me but it just seems like it would be harder to do it the way you suggest.
Because it will increase the size of log as it need remember the full path of processes.
But I think it is not a problem as we are not using 1.44 floppy drive.
For general use, it just seemed like another good idea to keep recently acted on processes in the Active Processes pane. After all, once I add this option, there are lots more that could be added 
Like keeping it for 5-10 secs?
It is not a big deal as we don't has a lot of processes that spamming the Active Process.

I think maybe you can add the function
1.To pin the process at Active Processes(always showing it whatever it is running or not(showing as not running))and showing a Bold line between pined processes/active processes
2.Create a new tabs(list) that can contain the processes(and maybe provide the function that always showing it whatever it is running or not(showing as not running)) that we are adding into that tabs(list), so we can see the processes by list.
Like
All Processes/Active Processes/Game/Media Player/Must running/...
And adding the function to running it by double clicking it(if it is not running), and maybe bring to front(and hiding PL window, select back to Active Processes) just like the Task Manager.
1. is because I found most of the time, I am seeing Active Processes instead of All Processes.
2. is I found if the Process don't list in Active Processes(as it is a short active list to keep easy to find the processes), I need a long time to finding it in All Processes and I know its name and function.
When I can't find it, I need a long time to click start button, typing the words, make sure it is correct and click enter to running.
Too bad the start menu only list Apps without the folder name(in the start menu).
