I never knew of such functionality...
but customizations of the board will be limited. The more we customize: 1. more difficult it is to upgrade 2. it potentially opens us up to harmful acts. So, no promises on customization. And, by the way - just because another site has a specific customization, doesn't mean it's safe.
So, no promises. But we are listening and we will investigate requests, as soon as the board is fully functional and stable.
