The current screenshot for xfce4-taskmanager is not in English, out of date and in need of a refresh. A screenshot is needed of the settings window showing available configuration options. https://docs.xfce.org/panel-plugins/xfce4-taskmanager See https://docs.xfce.org/contribute/documentation for details on screenshot requirements.
The right link is https://docs.xfce.org/apps/xfce4-taskmanager Anyway I updated the screenshot, please review it and if it is good close this issue :)
Looks great. I am going to open up another bug for this plugin request documentation for a ll of the different fields. Thanks!
