You can set no display and insert menu stardard way by menu manager (if center area has its own menu area).
In this case you can select main, minimal and default template.
Templates are in separate forum template file. Gameplus theme has not this template styled (only forum).
I did what I could. Not perfect.
Just playing with google custom search. It's searching this site, e107.org and github with e107 in repository name.
If you use any my theme: with version 2.2.0 there are core changes - comments and social icons - if you find problem, just tell me.
I will be on holiday until end of November. So no answers from me until then.
