My Lands: Black Gem Hunting

I don't know if I'm blind, but i can't see buildings/tech/trade cooldowns. It will be nice to have something that say "hey, remember that in 20 min your new resources will be here and you can build your brand new fortification!" or "Remember to unlock the new tech in 2 hours".

Exactly what cooldowns are you talking about?

From what you described it sounds like you want to see how long something will take to build or research -- if thats the case the game does that for you by telling you when it will complete..
