We don't really depart from what Marble is providing us with, UI-wise. OTOH, 
Marble isn't centered around *selecting* something on a map.

I agree with you. Our goal when rewriting the map interface was more technical 
(i.e. replacing kgeomap with Marble) than user-centered, and it shows. In the 
end I decided that the state as we have now is "good enough" to be usable.

Thanks for reminding us that we should really improve things in this 
department ;-)

This should get more intuitive by implementing visual feedback (i.e. changing 
the mouse cursor and highlighting the "active" cluster).

I mostly avoided/ignored the map code since moving to Marble - I guess this is 
a good time to revisit it and implement the visual feedback.

I'm not entirely sure whether the whole Ctrl+drag selection is discoverable, 
but I don't have any ideas on how to improve this. I'm happy for tips, 
though...
