• Removing the navigation bar so there's no weird double navbar when opening the wiki inside metaos
  • 
• Merging search into the sidebar or leave it where it is if not possible
• Redirecting https://wiki.metagame.wtf to https://wiki.metagame.wtf/docs/

If possible, it should look like this: If not possible, then only move it above the sidebar like so: If not possible, leave it where it is.
