Hide the navigation when calling data-derp from gather.town

[KrisSimon]

Situation: In every tour I mention that the participants should not use the navigation in data-derp, but follow the path of the houses and tables.

There are two reasons for this:

• Firstly, I want to keep track of the cohort and
• secondly, we want to be able to add additional content that is not reflected in data-derp.

In addition to mentioning it in the sessions, I always write this instruction in the chat. Nevertheless, there is at least one candidate in every tour who overlooks this information and is confused as a result.

Possible solution:
To prevent this confusion, it would be nice if the links to data-derp from gather.town would open without the navigation.

Technical implementation:
As a draft I wrote a feature, that disables the navigation when the page is called with a query parameter nav=false.

Discussion
The downside is that we have to edit every link in gather.town to add the new parameter.
Maybe it is possible to check for the referer, but I do not want to do this during a course and we also deal with iFrames, that could lead to misbehaviour of that feature. So a query parameter is the best solution in my opinion.

The page layout is not optimal:

The navigation at the right is too big.
