Cache Routes to allow for Tabs to keep alive while offscreen

[ziongh]

It would be awesome to have a functionality to allow multiple routes to be opened simultaneously so that the user can navigate between the components without unmounting and remounting them. This would allow for an Application to have tabs functionality similar to chrome:

I don't known the best way to achieve that, There could be a hidden component that when the page goes offscreen it holds a reference to the page, and when a navigation happens, it first looks for this offscreen "cache" to known if there is already a live component, otherwise load the component.

Maybe there is a better option, but this would be great, because the user wouldn't need to open multiple tabs, and this would decrease memory comsumption.
