I tried to implent a redesign for this hub. Here's a draft version: User:RichardHeigl/Draft
Two problems: the language box is not displayed, and I'm not shure about the translation marker tags (I deleted them in the draft).
If somebody can help me with this, we could redesign this page an the developer and sysadmin hub. They are among the most visited pages and haven't changed for many years. :-)
