[Suggestions] Improvements for the game

Here is my suggestion I hope you guys comment on it and we can start something here.

Can we at least filter the Global Market by supplier?  So Building Supply store, Farmer's market etc

We can really unleash this games power by taking the bottleneck off of the market. 

Also you can remove the cap price of some items and put in a time frame for the sale. 

This way people won't ask for millions for something stupid. So it if doesn't sell in 8 hours it's gone.

Thanks for your time

Also.

I'd like to see a ranking system in game of all cities so I can travel to them and also the ability of adding any in game city to my friends list with the ability to chat with them.

I am very large now and I would like to help smaller cities grow and right now the game is very young and limited but we can fix this!!

Thanks!
