Scriptish did nothing when presented with this userscript:
https://greasyfork.org/en/scripts/21391-youtube-comments-sidebar

Also, there were absolutely no instructions about how to install a script.

Greasmonkey otoh instantly recognized the script and installed it with a nice dialog and after one click.

So I went with GM and uninstalled Scriptish.
