Improve trail planning: option to re-order route anchors

[slothful-vassal]

Hi,

I have tried to improve the trail planning capabilities by adding a drag-and-drop list of trail anchors, which allows the user to change the order of the route anchors.

I hope you like it!

Kind Regards.

I have removed the 'snap to path' toggle again

• makes no sense (and was not working), if 'follow paths' is disabled
• should always be active, if 'follow paths' is enabled, which is the new behavior

I was just going to request this feature. Great, it's being worked on!

Back to draft, because of rate limitations by nominatim. We need a rate limiter for request against the nominatim demo instance, max 1 request / second is allowed. Before, this wasn't a big problem, but when retrieving locations for the anchors, we have too much traffic. This limiter has to detect whether the demo or an private instance is used.

• rate limit for nominatim calls added
• request cache for nominatim calls added
• retry added for nominatim calls added (sometimes, I've got ERR_HTTP2_SERVER_REFUSED_STREAM)

• fixed several issues
• fixed some speed issues

New Feature 1: option to add the location you searched for to the route (as trail anchor)

New Feature 2: option to use a POI (e.g. camp ground) as a route anchor

state handling still not optimal
