I've had a play with using the JustTheDocs Jekyll Theme[1] with the new website[2] - you can take a look at it here (still a work in progress):
https://niallkp.github.io/attic-justthedocs/
One of the nice things is that it comes with search, I like the menu down
the LHS and it has a mechanism to have a copy button on our template text
(see resolution page, other pages are TODO)
