That’s a reasonable argument…when you suffer from the sort of tunnel vision both seasoned players and myself share 
It’s based on the assumption that players just naturally know that this tool exists and that the fact that it doesn’t show up in any official communication or screenshots has zero impact on their decision to try the game. A player who, for example, arrives via Steam
- has never seen a dynamic map on the AirlineSim Steam page
- has no idea such a tool exists
- would have to get in touch with the community or stumble over a YouTube video to discover it
- switch to the browser to use it
- be fine with the fact that it’s an external tool that requires manual steps to use
That’s a lot of “ifs” for a feature that many will deem absolutely mandatory to “properly” play the game. Hence why it is on the roadmap with a fairly high priority and some prep work already done.
