 I have the feeling this was already discussed somewhere, but can't get my
 hands on it, so I'm posting it as an enhancement ticket:

 It would be really great if the zoom in different displays could be linked
 to each other. In other words, when you have different displays open, an
 option should allow to link (all or some of) them so that when you pan and
 zoom in one display window, the other display windows are panned and
 zoomed in the same way. This is extremely useful when comparing maps.

 Currently, you have to zoom in one display, save the extent to a named
 region, then zoom the other display(s) to that named region. Possible, but
 a bit of a hassle.

 <brainstorming>One possible implementation would be a check box in the
 menu at the bottom of each display: if checked the display is part of the
 "common zoom pool" and if the zoom or pan is changed in any of the
 displays in that zoom pool, all displays are changed.

 Or, probably easier, a general option to link all displays.
 </brainstorm>
