[Qgis-user] Re: Feature inquiry: Multiple display windows?

[Agustin Lobo]

I share the interest on having linked displays, Sjur
mentions several geographic displays (which could be
even at different scales), but this could also be
linking an scatter plot and the geographic display, for example.
Could these ideas be included for the 2.0 roadmap?
