Describe the feature request

It feels awkward to kill processes with the process view, because, depending on how the processes are sorted (e.g., by CPU), they can jump around. Locking the relative positioning of the process, like HTOP does, would make it much easier to confidentially kill a process without worrying you might accidentally select something else.
