Hi Sophia, Gerrit and Loni,
Thank you for giving feedback about the additional filtering, grouping, searching needs. As you can see this is quite a popular opinion to add these to MapHub, but to support these features the UI would need to have a big rewrite. I’m not saying it’s not possible, just that it’d take substantial efforts on our side.
Right now we are concentrating on fixing bugs, but it might be possible to add features like this in the future.
