Good point, I can't count how often I've left a ship on planet for a few turns because it wasn't auto launched. Actually, I would also like to suggest that the auto-launch option be set as default, or an option be made to choose which you prefer as default.
In regards to the icons that fall down the right side, I would also like to suggest that they disappear each turn, whether clicked or not. If you are building a war fleet, often you will be making dozens of ships at one time. This fills the whole side. Next turn it becomes overflowing. The turn after that, you can't even see what's happening.
