Individual text size for tabs or window


Hi all,

When I do: crtl + scroll for change text size, It change text size of all tabs or windows;
Can you make an option that allow only change text size on current tab/window only?[like when we browses a site then crtl+scroll for bigger text for that site only].
I thinks that will help a lot when we need two windows or tabs split-ed and the length of line is different.

Thanks you.
