hey BJ, i hope this is a good place for this...
as i understand it, the _AutoExec in the Internal.xml is executed whenever MXM loads and _AutoExec can be overridden with one's own custom script. in the next release, could you include an _OnExit internal script that really does nothing, but can be overridden?
here's why i think that would be cool...
an autoexec script could be written that prompts if you want to 'login' so to speak. when one 'logins', the script could load a 'user profile' that includes things like mxm.xml, menu.xml, etc. and game-saves from a backup location. when MXM exits, another script could ask if one wants to 'logout' which would entail backing up current saves, etc. and restoring the previous settings and saves.
what do you think?
