Portrait mode in LK 2.0
Portrait mode is fully supported by LK, and it is now perfectly usable instead of landscape. Portrait mode is the default choice on some old palm pc (PPC), although some of them (namely HX4700) can rotate the screen to landscape with no problems.
OLD IBOX MODE
Old XCSoar interface, called IBOX mode within LK, is still available. Simply select IBOX mode either from menu or from a custom key, and you can jump to the old look and back to LK in less than a second!
In IBOX mode all functionalities of LK are not available, though.
