I want to suggest to place the TOC generally on the right side of an Wikiarticle. Some other wikis don't do so (like wikipedia or ) but they have on the right side allready a Box displayed and the user have an option to hide the TOC. On widelands.org we do not have such a box on the right (what for?) and hiding the toc is currently not possible.
The screenshots are based on the article https://wl.widelands.org/wiki/GameHelpbasicInterface/
If Images or Codeblocks are wider than the place between left border and beginning of TOC they slips beneath it:
What do you think about this? If you like it, i will place a bugreport on launchpad with the appropiate adjustments.
