Pretty self-explanatory, a part that provides thrust with Space key by default. As of now you can't use this in the existing planets, there will be a rocket planet in the future. We just wanted to already let you play with it in the Sandbox :) In the missions rockets will have limited fuel, but Sandbox has infinite fuel. [*]"Drop a box" -feature that drops a random box behind the rover, so that you can easily test lifters [*]Sandbox mode is also ideal for stylish screencasts! [/list] UI / Usability features: [list] [*]The driving camera is now easier to rotate around [*]Rectangular selection tool (Shift+LMB) in the building mode: selects everything that's inside the rectangle, also parts hidden behind other parts [*]Camera now rotates with arrow keys in building mode [*]Other new shortcuts in building mode: F = Flip, O = Options, +/- = Zoom [*]Options-menu tweaks: better handling for situations where there's multiple parts' options shown [*]Double-clicking a part now opens the Options-menu [*]Rover Gallery scrolling now works properly [*]Disconnected parts are no longer removed when driving/saving
