Is your feature request related to a problem? Please describe. Easier the navigation through differents documents linked to the same route (for outings) or summit (for routes)

Describe the solution you'd like add arrow buttons at the bottom and top of outings and routes documents to easier navigation in order to go easily to the next outing linked to a route or the next route linked to a summit

"documents linked to the same route (for outings) or summit (for routes)" Should be waypoint instead of summit in case of routes IMHO

[panglesd]

Routes can be linked to several summits, and similarly outings can be linked to several routes.

I think remembering the search that lead to a specific outing/route and use that for the next/previous document could be a solution.

For instance, one can then navigate all routes linked to a waypoint, all outings linked to a route, but also all outings within a region, all routes within a specific grade range...
