I don't have the option to delete nor edit my comments, so I'll have to post another one.
I noticed the "Community Hub" link at the top was redundant (there's anoter one labeled "View Discussions"), and also it doesn't depend on the SteamDB extension. So now my script turns "Community Hub" into a link to gg.deals. And the link has the GG logo, matching the style of the links beside it. It got bigger than the other two by accident (don't know CSS enough. I liked it though), and the tooltip doesn't appear. In fact, I spent more time trying to fix the tooltip than to do the rest.
I'm not so familiar with Pastebin, but it seems the same link will have the updated code
Pasting as a link so that huge preview doesn't load again
