Cache dashboard results to improve performance when switching tab?

So radio buttons should only refresh the page you're on...whereas tabs try to refresh everything.  This is where I think it could provide some time savings for you.  

When you set up the component, you define the buttons options with a param.  Typically I'd just use a param type = delimited list.  The param can be hardcoded with the various options, or can contain variables if you want the list to be dynamic based on other selections.
