I have two accounts; one of which has the newest update to the mobile ap, allowing for a set-all feature, and quick scroll through factory sets.
It has made the mobile play so much easier and quicker, especially on the run. Swipe through to collect, click one building, set all for the workshops rather than clicking through individually makes it easier to play -- I wished I had had it during the event, it would have make it so much easier in my bigger cities.
The ability to click on one factory and then simply scroll through to set, just lovely -- and I am hoping it launches not only to the rest of the mobile ap worlds, but to the PC version.
The other item which would make the PC version great, would eliminate the very, very, slow graphics in the battle modes. Either make the moving unanimated or speed increased even further. Battles are fun, but so very slow.
