Navigation
Located in the upper-right is the menu from which all current, past and support operations can be directly accessed. Clicking on any of the major sections (Active/Inactive Vessels, Crew Roster, DSN) will drop down the contents within. Double-clicking a menu item with a + or - next to it will give you access to additional sub-content. In the case of bodies, even double-clicking the name will take you to the body. If you only want to see what objects are in orbit around a body, clicking the + sign directly will open its contents without selecting it. If you need more room for easier navigation you can expand the menu to make it taller, which will hide the twitter feed until you choose to collapse the menu again.
Filters can be accessed with a link at the top of the Operations Menu and let you control the menu contents for active/inactive vessels and crew. The Active Vessels filters help to declutter the menu by showing or hiding various types of vessel from the menu depending on whether their type is selected or not. If there are no active vessels of a certain type, that option will be disabled. If enough vessel types are removed that none are visible under a certain body, that body will also be removed (except Kerbol). The Inactive Vessels and Crew Roster filters serve a different purpose and re-sort the entire menu section according to the option that is selected. If you are looking at the Full Roster while doing this for crew, that will be re-sorted as well upon selection of a new filter.
