In an embodiment, identifiers and states of processes are displayed in a
stacked cursor, which is moved in response to movement of a pointing
device. The display of the identifiers and the states is customized based
on a presentation type associated with each of the processes. If a time
threshold associated with the process expires, the identifier of the
process and the state are removed from the stacked cursor. In various
embodiments, customizing the display of the states and the identifiers
may include displaying the state and/or the identifier in text forms,
icon forms, and/or colors indicated by the presentation type and/or
presenting a sound indicated by the presentation type in response to a
change of the state. In this way, a user can determine the states of
multiple processes without diverting the user's attention from the
stacked cursor.
