Would it be possible to also display how many you lost? Or maybe a list of the games like a ladder page?
I agree it would be a useful feature -- feel free to add to Uservoice.
Would also be nice to be able to see quickmatches of other players
This is something I want to do as well, I just have to prioritize critical fixes first. Feel free to add to uservoice too, it's helpful for me to get vote data so I can prioritize things correctly.
you can no longer copy and paste chat
Copying chat can be done by long-clicking the chat message. I'm not sure why you can't paste -- what problem do you run into when you try?
When group deployments happen, the number of troops added stays above the territory until all deployments finish. This might be intentional to give you time to read them, or just due to the game only being able to do one thing at a time, but if they can vanish faster that'd be nice
It is intentional. I'm not sure why you'd want them to vanish faster, can you explain or show me a screenshot of where it would be beneficial?
In flash you could hold the arrow key to go through the turn or history really fast
It should still work. Can you clarify what key you're holding and where? (history vs watching latest turn, for example)
Clicking on a players name no longer shows how many territories they have
This was moved to Game -> Statistics. I know it's painful when things move around, but give it a shot and let me know if you're able to get used to the new location.
