Things like that would make interesting additions to YR, but as we say, really you need to work with PD and submit patches to his patch. He's already done a lot of work on features you might want to use, so there is no point you duplicating his work and it would benefit everyone with additional features you want to implement that perhaps PD isn't interested in working on. There is no point in modders having to choose between two patches with different feature sets.
Edit:
IF you are working on adding to the way missions can go, useful features would be making Global variables saved into a save game file so they are not lost if you save the game. Currently globals will carry over from mission to mission, but will not get saved, so loading a saved game resets the global value.
