Review for Scriptish by Shiro
Rated 4 out of 5 stars
Underlying components are better than greasemonkey. I especially like the update function.
But it's missing a few things that are available in greasemonkey such as a mobile version and sorting in script management.
Another thing that bugs me (but it's really not a problem) is that the "active script counter" goes beyond the button area.
