Idea - Settlement upgrade and visual improvement

Hi,

i only played Elemental for about 1 hour per week since 1.09 to 1.1 [on kingdom], I might be still not understand the game fully yet

but just to share my concerns.

1) How do we know if a level 4 city compare to a level 2 city?

2) City can only be bigger and bigger to advance in level? (with huge influence zone)

In some of the city building games like Caesar 3 and Anno have settlement upgrades with visual indications to allow more dwellings.

(some games have roads, market visual improvement as well)

I am thinking it could be great if we borrow the idea - probably for 3 level of settlements (Hut to Casa to Villa for Kingdoms)

This will save some lands and make the city looks more elegant / less cluttering rather than just keep getting larger?
