DMS has this built in, idle inhibit widgets and IPCs. Is there a reason for this over that one?

@firemonster612 can you elaborate on what is the difference of this plugin and the built-in functionality? we want to avoid adding redundant plugins, but that is ok if we have a clear reason even if minimal, and on that case I will ask you to add to the description.
