Not true. If you've never been to the site before, you don't know what calls it will make, or whether you need them.I have either allowed it, which means I don't mind it being accessed when it shows up or untrusted it, which means no matter how many times it shows up, its not going to do squat, so either way I am covered.

You can't "untrust" an individual object in NS itself (vs. ABE, which is not on the table here). You either uncheck "Forbid Flash" (or whatever), or you don't, and you either "Apply to whitelisted", or you don't.If I want to TA something I have previously decided to untrust, then I find it under untrusted menu, I TA it and move on, or if it has a placeholder, just click that, it automatically TA it and when I am done, goes back to the way I had decided in the past,
I think we're talking about two different things here, so I have nothing more to add to this. So long as you don't object, then there is support for the RFE, and no objection.
