UPDATE: Version 1.0.14 is now up. This version automatically purges the cache on your wiki page after updating your data just in case the wiki has out-of-date information cached.
adambiser: True, I ditched the separate "My Games" and "My Shelf" on my version of the script and just kept the original "My Games".
It will be a bit of work so I'm leaving it for later, but I'm thinking of changing "Community" to a drop-down and moving "Messages" and "Forum Replies" into it. That would also be a decent place for the site wishlist.
adambiser: Also, how does one completely disable the auto-hide? Right now I just commented out that section of code. I didn't know how to tinker with the settings there to do what I wanted. I guess I was looking for a checkbox that said "Enable auto-hide" so that I could uncheck it.
Look in the Greasemonkey menu (from the Greasemonkey icon on your toolbar or status bar, or alternatively from inside the "Tools" menu of your browser) and open up
User Script Commands. You should see an item labelled gog.com:
Configure menu autohide. Click on that to bring up a configuration control, then change "Opacity when hidden" to 1 and "Offset when hidden" to 0.
