Tab Snapping

New feature request.

As with Windows Snap; I'd like to be able to view websites in one window but simultaneously. 

Having tabs move to new windows - sure that's an option but you have to resize all your windows as well. 

i'd like to right click on a tab and snap to left or right if there are more than one tabs open. right click and un-snap.

The current page would resize to 50% of the browser window width but enable you to resize the tab width as desired. 

This will help with tabbed multitasking on a tablet device and those who use the tablet mode in windows.
