Multiple tabs heavy memory usage

Not sure if this is a bug or not, my computer is having memory maxed out when I have multiple ZZTakeoff windows open. Is there a workaround or a method to have tabs that are not currently being focused on not require such high memory? I often have multiple tabs open to view various building angles/spaces when performing piping/electrical takeoffs. Perhaps a feature that allows page tabs within a single browser window would reduce this memory demand (not sure if this is already a feature!)
