On the main screen toolbar, click on the Planet/Shiplist Button.
When you click on a planet in the list, the main map recenters on that planet, and the shipyard is available in the regular place onthe main screen. You can quickly go through the list.
You can sort the planets by different categories in the list on top of the Planet/Ship list screen. Rally Points are one of the categories you can sort by.
You can do the same with the Ships by clcking on the Ship list button on the top. For instance, you can show just the ships orbiting - when you click the ship it brings up the planeyt in the main window.
