this is a VERY useful addition to greasemonkey (GM). The only thing i don't like about GM is that you have to find scripts for sites... Its time consuming, and you really have to kinda hunt some of the stuff down... im lazy, so its much easier to be able to install this addon, and know whats available for the site your looking at right now and not have to try and remember or stumble upon something when you do decided to look at userscripts.org.
Of course, i also like that the author uses a local index to see what applies to the page your looking at, so your not querying the some other site.
It also lets you view the scripts page to be able to read more about it. Very good stuff...
