Energy Saver - not visible whether active or not

How or where do I see whether the Energy Saver is active or not?

If I klick on it in the Toolbox menu, visibly nothing happens.
Depending on the setting, windows are hiding and are coming back (once I click again), so I it seems to work.
However, there does not seem to be any UI element showing me whether the Energy Saver is active or not. Only way for me to find out is to look in the list of processes where it is listed (if active). Is this working as intended?
