Turning off Cache Frames when Idle

It took a while to figure out that the way to do this is: Composition Menu > Preview and turn off Cache Frames When Idle

And this setting _should be_ in the Disk Cache settings as that's the obvious place to look for it. Why would you put other controls for Cache Frames when Idle there but not the ability to turn it off? Especially since turning it off seems to turn it off globally, making it even stranger that it's not in the Settings. Just confusing IMO.

 The feature can be useful but it's really a memory hog, especially with 8K+ comps, so it should be easier to turn it off. (I mean, once you know where it's hidden, sure it's easy, but it's not easy to find)
