Well, thanks for it.

I see I was in the wrong column when doing the "supports
turn-restrictions".
BTW: how do you do that? I tried to understand that part in the sourcecode
but couldn't figure it out. What algorithm are you using anyway? Dijkstra
and A* cannot support restrictions on nodes and I could never find a
description
of an algoithm named "B*" that is supposed to do that.

What was your intention when changing Gosmore "supprort for house-numbers"
from "no" to "??"? clearly the gosmore sources do not contain a mention
of "addr:housenumber", so it cannot have support for routing you to a given
housenumber, can it?

Well, we had 10(+1) offboard navigation-application in a plain list.
I merely expanded on that so the users have a chance to see what these
programs can do or at least what platform they are written for without
visiting and learning about each of them.
A major turndown for a user who simply looks for a navigation or routing-
application to USE.

For half of them I couldn't even figure out if they where supposed to be
used
on a mobile phone, laptop or something and if they can handle a complete
continent,
country or barely a single city in the first 3 minutes while reading their
website.
