I find the new ship built icon to be inconvenient, in that when you click on it, it brings up the shipyard's production. This is not what I expect. Since we have to launch ships from the planet before we can do anything with them, I would much prefer the new ship icon to cause the screen to center on the planet that built the ship. Often, I am building the same ship over and over again, so I don't really need the shipyard interface. However, I do need to be able to find the planet that built it among the zillions of worlds I control. This gets harder and harder on larger maps...
I consider this a fairly serious negative on the interface quality (which I did also bring up in beta 2), seeing as it can become quite tedious to find that new ship.
