Good day! I'd like to suggest adding a feature for upgrading the walls. A button wherein you can upgrade walls in a row with your gold or your grog, whichever you like, or which resources you have the most.
Multiple wall upgrading has been discussed in other threads and is something we will include in a future update
@Chris [Midoki] Is there any rough estimate as to when the next App Store update is coming? Just out of curiosity.
