[Qgis-user] Analyzing two cities side-by-side?

[David Epstein]

Hello,

I'm simultaneously working on data for Minneapolis & Cleveland (USA). 
I'd like to display these two cities side-by-side to scale nearly all 
the time. I'd also like the display(s) to share symbology ranges and 
eventually a common legend. I know it is possible to create two display 
windows for distinct spatial datasets in GRASS. Is there an easy way to 
do something similar in QGIS? If not, are there other open source tools 
for this approach? Perhaps SAGA?

thank you,
