MapView: ordering of layers

In the Mapsui.UI.Forms.MapView, the ordering of layers is the following:

1. user layers (base maps + overlays)
2. drawables
3. pins
4. callouts
5. mylocation

From my point of view, there are two issues with this:

1. Mylocation is on top of everything else (possibly hiding drawables, pins & callouts, which I find kind of unnatural)
2. The ordering cannot be changed (any more), since the original ordering is restored in MapView.HandleLayers.

Before v3, changing the ordering was possible, and in fact I used to do this via Map.Layers.Move. Since #1185 was merged, this does not work any more. The ordering is always restored in MapView.HandleLayers.

There are two possible solutions that would fix this for me:

1. Change the default ordering so that mylocation is below the drawables, pins & callouts.
2. Have a way to change the default ordering.

Which one would be preferable?

This issue is fixed by #1494 for me. I think it still makes sense to introduce further improvements like layer groups, which should be discussed in #1491.

Ok, from my side I see no problem. Should work. And if it helps.

Alright, it would definitely help me. I just submitted it as PR #1494.
