Hiding boards

Is there a way to do this?

Now that there's so many boards in the catalog there should be an option for people to hide the boards they don't visit to free up some of the clutter.

I know, I'll add an option to edit the main menu soon.

Right now you can add something like this to the Custom CSS box:

#topnav .button[href$="/"] { display:none; }
#topnav .button[href="/a/"],
#topnav .button[href="/jp/"],
#topnav .button[href="/g/"]
{ display:inline; }

The first line hides everything. Other lines define which boards to unhide.

Thanks, that's very helpful
