The documentation is some of the best work I have seen in a long time when it comes to providing information and functionality. There is just one thing I would like to request. The Basic and C++ Buttons at the top are a good start but would it be possible that if you select one or the other to have it stay in ether mode while browsing through the documentation? I figure that it's still a work in progress and wanted to suggest that just as feedback after using it for a bit.
Thanks and keep up the good work.

Tried to store the setting using cookies, but this proved to be a problem on some browsers as they didn't allow for local cookie storage. Expect there is some way of handling this, so expect to see it implemented in the future.

Ok, no problem.
