#1 The planet/ship list below the minimap quickly fills up with entries. I found myself scrolling through and having to search for newly built ships and those that were idle. I suspect from the layout that there will be some default filters added later in the same way as the 'Available Projects' list on the planet screen. What would be nice is perhaps a custom user filter. Allow the user to show a number of combined filtering options e.g. Idle & New ships, Discovered uninhabited planets in systems where you have colonised a planet.
#2 The turn button presently indicates idle ships/production queues. Highlighting these entries in the list and/or moving them to the top of the list would make them easier to deal with. In addition perhaps highlighting the tabs at the top of the list to indicate if a ship needs attention whilst displaying planets.
#3 Following on from #2. The list takes up a chunk of the screen if it were an option to roll this up and just leave the tabs below the minimap at the top it would allow a wider view of the galaxy.
