The first thing is that I think it's a bit annoying when the map tilts 180 degree on selection of your unit or on viewing enemy approach. Is there any way to bypass this and if it isn't then can it be done possible to do so.
And to the second question is about making it possible to see on the city panel on how many market nodes a city can provide.

When mouse-over the City on popup you can see current/max market nodes,its last in green like "Y 3/4".
