I am looking for a way to list all parts currently (in-flight) consuming electric charge and I have been given a hint to have a look at Fusebox. I can use Fusebox now to at least switch whole categories of parts on and off to check whether the power-guzzling devices reside there, which is for sure a great progress compared with checking each part manually. If, however, you might sometime be looking for new features to implement, such a list of active electricity-using parts including their current level of power-usage might be useful for others as well.. Just a thought ....
