/*
 * How to avoid having really two different objects
 * for Extended and ExtendedAll
 * The only difference is the Lister...
 * a) static object?
 * b) leave some object inside the OFileSelector which can be used?
 * c) when switching views tell which view we want o have.. internally we can switch then
 *
 * I'll take c) -zecke
