Avatar hiding obsolete
Now that Groundspeak has added the ability to hide avatars via a profile setting the capability in your script is redundant. In fact it breaks the avatar hiding capability of the web site by showing the avatars when the profile has been set to hide them. You should either remove this capability from your script or enable it to recognize the setting in the profile and give it precedence if it is set.
Ah, ok - I just add a comment to your review.
Sorry, I don't get any mails from userscript.org, so I didn't notice any new posts here.
This option is required, because I need to rewrite the gc.com-Code of loading Logs for the VIP-List. So the Option of gc.com will not work with GClh.
