SEXP-based strikes are super easy to manipulate, but I'd just like to be able to render inoperative all TAG-C with a single SEXP. I know it's already doable, I can think of a few way to do something like that already. I just think it would be prettier to have an ON/OFF switch

.
Anyway, as I said, if I ever get the courage to dive into the source code, I would probably write a small patch myself (if that's still on my mind then), which may or may not be accepted in that distant future anyway.
EDIT - actually, there's a few more thing I'd like to be able to do with SSM, like being able to set a mximum number of active strikes, a general cooldown system (independant from an individual fighter's TAG cooldown), messages to be played if a SSM strike can't be fired. Part of all this can probably be done through scripting, but Fred and table-based solutions might be more handy, especially to newcomers.
EDIT 2 - but I think we are getting off topic here, and this might not be the best place to discuss all this :s.
