Starting with Change set 25, players will see a shortcut link to attack a country after getting a successful regular spy op on it. That link will take players to the war room with the target's country number already entered. Viewing the saved op will also show a shortcut link for getting a new spy op with the target's country number already entered. Screenshots:

Is this helpful? I'm very interested in the moment in making small changes to make the game easier to play, especially for mobile users.

Yes that will be very helpful for mobile user group saving have to scroll down to another tab

I would say yes, and would prevent typos on country numbers.

Very helpful.
