I am always using the "Hide All Types" command when modelling but I don't like how cosmetic threads are grouped in with it.  I was looking into writing a macro that would toggle on and off the visibility of whatever I have shown, leaving the cosmetic threads always shown.  To do this, I need to be able to store information on what is visible or not.  I'm not sure what would be the best way to do this.  I've come across IGet3rdPartyStorageStore but I don't know how I would go about using it.  What would be the easiest way to temporarily store information on what was toggled on and off?
