Optimize mobile navigation on documentation site

[bjarnef]

When looking at the documentation site from mobile it is very difficult to navigate as one will only see a few pixels of the navigation at top of page.

Hi,

Sorry about that. It is planned to complete work on v5 and then create a new website to better present new features.
