Zoom and tile info

Would it be possible to add zoom to enlarge the graphics or an option for different sizes, also some tile information when you click on a unit or blank tile. The reason I ask is that I built a city on a tile that had no food but missed that fact and now the  its is not able to grow. If this feature a ready exists could some one point it out for me please. 

The game is awesome and I'm hooked, keep up the great work.
