I was very pleased with UI showing resouces/second and units speed.
Why not also showing units training time, technologies, etc. right next to their cost?
I guess building times are more tricky since there are different villagers, some military units can build too, several wagons, etc… But might be possible too.
I think this would be relatively easy to implement and community would appreciate.
I hope they add this as it is very helpful information when playing.
I made a thread for this as well:
