@korina After quick inspection of the requests made during dataset switch, I believe the online feature would not require ton of work, since the data appears encoded in the jpegs. I do volunteer to help implementing the offline mode. Pretty sure other mariners may jump and contribute as well..
The question is whether Windy will feel comfortable opening a snapshot of the site code, so we can begin collaborating on this feature. Getting started directions on how to setup a development environment would suffice, so your overhead would be minimal.
If opening to the public is something Windy will not do, I am ready to sign NDA and begin collaborating with you under it.
Let me know your thoughts.
Thank you,
