Destroyed object/crashed aircraft craters/smoke

[FuriousMeow]

In GB both of these disappear pretty quickly. I think the reason was there was a limit on how many could be spawned? Supposedly that limit has been expanded or completely been removed?

I'm not sure how much performance impact they would have but if there's also a timer on them regarding performance would it be possible to add that as a setting so there's a few options depending on one's system's capability? Like shortest, short, medium, long, indefinite/until mission end? The first 4 options being 1 minute, 5 minutes, 10 or 15 minutes then 30 minutes?

Just spitballing here but it would be nice to be able to control that *IF* there isn't a hard limit. Although if there is a limit I guess if its possible to despawn the oldest when a new crater/smoke column is made that also works.

Something else I'd like to see is 'static' smoke trails hanging in the sky for a while from a mid-air burning/exploding aircraft.

It would be nice if static objects had more detailed damage model, with same destruction physics like dynamic objects has now. Smoke and dust also should look more realistic, the smoke scale is not particularly right.
