SAVE gave features desperately needed

My brother finally got this game courtesy of me, and the one thing that burns him up about it is the lack of a comprehensive save/load system, if the only way to save your game is to quit, and the only way to quit without saving is ALT+F4, that really ruins the fun of the game.  We need a Save/Quicksave and Quickload feature without having to resort to exiting or quitting a map in order to do so!  Please make this happen!
