Is your feature request related to a problem? Please describe

Often users want to view different parts of app at the same time if they have the screen space to do it. modifying nav_item's to allow this would be a useful feature. It would need to come along with a developer warning in the docs to remind that the new window or tab is a new client and thus any client state info is lost. If the app has little or no state preserved in the app then encoding the state in the hash route might be sufficient

Describe the solution you'd like

right clicking on a nav_item would allow the user the option of opening the target of the nav_item in a new window or browser tab. This should be an optional feature since if the app has a lot of state information in q.client then that will be unavailable in the new window or tab

Describe alternatives you've considered

Button with path provided can be used, but that only allows opening in a separate tab
