At the present you can only build 99,999 units per time in the shipyard. With the universes evolving and resources are running in the trillions by now I would like to suggest to up the maximum 99,999 items (per click) in the shipyard into 999,999.
If you have like a lot of resources and you want to build e.g. 10 million light fighters, you have to input the current information of 99,999 like 100 times. And while you are at it, can you make the items you get in the Market also a bit more interesting? The Bronze items are as good as useless, just imagining if you had a line of 100x 99,999 light fighters, that half an hour detroid would not even scratch the 10 million seconds (or 2,777 hours) you need to build for example those light fighters.
