Request: Give us access to default explosions.

[Argh]

I'd really like access to the default explosions / fire / smoke, which is all hard-coded. It'd be nice, for example, to make trees that catch fire obey damage restrictions like any other Explosion, use a custom FX script, etc.

This should be very easy to do, I'd think. If you guys need a default FX script, let me know.
