Just thinking about a new feature for this new feature that might coming. ;)

We has "All Processes" for checking mostly all processes, we has "Active Processes" for checking processes that are active, but we don't has the "Monitoring Processes(or a better name)" for checking the processes that we want to monitoring.
This ensure the list will be clean and static, to helps us keep an eyes on the processes that we want to monitoring without scrolling up and down. :)
