Thank you very much! This looks good already! :)

I only ran into one problem. The ordering by location is already working, but the locations are not sorted alphabetically but instead by poi_id. In my case "Test" was sorted before "Entwurf", as it had the lower id.
But, when I tried to find a fix for it, I ran into a few problems and I couldn't find an easy solution. Does someone have an idea? :)

Ohw 😓 I didn't read the issue conversation carefully enough, thought that it's enough to group by POI and after that sort contacs by name whithin each POI group.

As POI objects do not have any name (names are provided by translations) I don't think sorting POI by name is handy enough. It rather makes sense to add filter by POI.

Yes, exactly. That's why I also didn't find an easy solution for this. Should we wait for the second reviewer for an idea or should we ask UI/UX / Service if it's okay this way? :)

@osmers
Should POIs be sorted by their name at any cost? I know it's better but saldy not technically cheap. (and sorting by name means POIs will be sorted in different order depent on the language)

Thank you! 🎉

Re: the sorting iussue: maybe we could use this as an opportunity to add client-side sorting to all lists of this kind? I.e. allow users to cklick on any table header field to sort/reverse-sort by that key? AFAIK that should be relatively straight-forward (and a very common / expected feature anyways)

I think this would be the best solution, but let's see what @osmers thinks :) While we were planning the region condition @PeterNerlich and I considered something similiar, so it might me good to implement it in all desired places at the same time :)
