[Greasemonkey] Universal Exclusions List

[mfaq14]

(In relation to the security problem for non-javascript-literate people.)
Would it be possible to add a 'Universal Exclusions List' applicable to 
all the greasemonkey scripts to which power users with a weak 
understanding of javascript, or general users, the ability to easily 
block the scripts from working on very important sites such as online 
banking sites, shopping sites, etc if they so wish?

At the moment I do this for each individual script but I have quite a 
few scripts and want to exclude quite a few sites just to make sure, and 
trying to remember to temporarily disable the scripts every time you use 
an important site will invariably fail at some point.

Just a thought, please consider it, thanks, BrokenUnity.
