Improve "Tails documentation" browser
Since 4fba04a3, people get either the online or offline documentation when opening the “Tails documentation” launcher from the desktop.
When people get the offline documentation, I think that it should look as much as possible to the online documentation to obey the “Consistency and standards” UX heuristics: https://www.nngroup.com/articles/ten-usability-heuristics/.
People are really used to navigate information from a browser and we should provide as much as the common navigation elements as the online documentation as possible.
Currently, the “Tails documentation” browser lacks the following navigation elements compared to the online documentation:
- Sidebar: it is the only way we have for people to jump, for example, from /doc to /support.
- Tabs: tabs are heavily used by millenials when exploring complex content: https://www.nngroup.com/articles/multi-tab-page-parking/.
- Search: but this might be impossible to provide offline…
- Banner which includes a link to our homepage: but we have another home link at the beginning of the breadcrumbs so it’s probably not that bad. Including the banner would further increase the similiarity between the offline and online version. Removing the banner in the offline doc allows for more space before the fold, on the other hand, the space taken by the banner should be good enough for online doc anyway.
Having the sidebar and tabs would have prevented navigation errors in the user testing that I did of the Additional Software beta.
