The suggestion is about be able to change submitted tasks in construction queue for shipyard.
That means... if you have 9999 LC + 9999 SC + 5 RIP's ongoing... be able to reorder the tasks getting (for instance) 5 RIP's + 9999 LC + 9999 SC, just drag them on the queue.

Hmm, well ... If you pay enough attention there should not be a problem. It´s about planning, which is an important part of the game.
I have rarely been in a situation in which this new suggested option would have been useful for me. So overall, it is a no go for me.

Strange idea and i don't think this will be implemented.
