Even though Gathering storm has its own queue system, this mod queue is still superior. While it does not allow for multi-queue (which is not so useful to be honest, I'd rather click on individual city to see their yields n buildings Then decide on production), it does allow stacking buildings behind its prerequisites, unlimited queuing, and revealing of queued's district/ wonder location when hovering the mouse above them in queue, all without having to swap to a queue tab.
Hopefully it is still compatible to Gathering storm, and hopefully the official dev crew update their queue.
