How did I miss something like THIS?
I would be glad for this, even if it comes with a diamond cost. It gets tedious when you have many friends that sometimes I just log into the app to aid/sit in tavern from a right to left motion (yeah, swiping to the end of the list on the right and then tap each player then tapping the aid/tavern buttons and repeat), which is faster than just clicking on aid/tavern on the browser and sometimes missing a beat if the button misses to register.
For those wondering about the quest's "aid x players", you can still aid manually to complete such requirement if you're looking to preserve such during event quests. Like the collect all button (that costs 5 diamonds), I just separate the 1-day goods production from the 8-hour ones by manually collecting from either one (I collect from the 8-hour first), start up the productions for the group, click on the collect all button, then select the time for the remaining productions (I just select 1-day), and I am all set. I am hoping it would be similar.
Since there are going to be three groups, it will probably cost a bit more than just the collect all button, if each are programmed individually. Else, if they programmed all three groups into a single button then it might be the same as the collect all button. Then, there's the placement of such button and the algorithm of it figuring out if it needed to be necessary to be clicked (like the collect all button that detects when a single building is done) or if the player have to wait in order to use it (by checking on their own).
I am all for it if it comes without a hitch, but knowing the track record, it might come broken that will take years to fix.
