Would like to suggest the addition of a sidebar in Firefox for NoScript. The intention is that it can be made visible to show real-time information about sites -- which domains are loaded, which type of script technology are used, the blocking/unblocking or trusting/distrusting of domains on the fly, etc. It'd probably be similar to the menu pop-up but always visible and can maybe be used as a UI for managing the untrusted/trusted sites lists, etc. With the onslaught of widescreen monitors, I think it'd be a fine fit.
Perhaps it could also include a search box for searching the forums for help... using Google of course (so those 'words too common' messages won't pop-up)!

I'd also like to suggest the ability to turn certain technologies on and off for a specific site. I'd like to control whether Flash, Java, Javascript, iFrames, external domains, cookies, or even images are enabled for that particular site, instead of 'everything trusted or not trusted' as it is for most cases. As it is now, I can control cookies via Firefox, but NoScript is way more convenient as far as accessibility goes.
It sometimes seems like there should be an overhaul in the UI management for NoScript (like moving most of the configuration to a site-centric list rather than within global tabs), but overall I'm very happy with it. Thanks for a great product!
(Maybe some of this is already in the works along side the URL specific permissions, or perhaps it'd be too much overhead or complexity. Anyway, just some ideas...)
