Thanks for your feedback. I agree with much of what you describe.
I would tell you to volunteer and help but since you already mentioned
you do not have any interest in taking up this or learning JavaScript in
order to do so, I guess there's no need for me to ask you to volunteer :). 

I'll take a close look at the scripts and xul/css used for the UI in
NoScript, and maybe take some of this and merge it into
LibreJS. But ultimately LibreJS works differently than NoScript. NoScript
blocks scripts at the request level, that makes it a very different beast.

But yes, if we can come up with a list of improvements to make (Zak
Rogoff and other folks at FSF have already sent me quite a few
suggestions I'm working on), then we are half way there.

In the past few versions, LibreJS started using SHA1 hashes across the
board to cache whether a script is free or not, whether the script is
inline or external. This means that only now do we have the possibility
to whitelist/blacklist a single script, as you suggest. The toughest
part is done and we're almost out of the woods and on our way to make
the improvements we suggest.

Anyone willing to volunteer is of course, more than welcome to do so.

Let's try to get LibreJS 6 to fulfill what most of you expect and hope
