I would love if there was a feature made to render all of the server's chunks to a big image and have that image browseable in a google maps interface, kinda like dynmap does it but in AntiqueAtlas' style!
Optionally with server set markers that go for the web map only.

Ooh, I would love that! :)
If dynmap allows using custom tiles in this way, then feel free to use our textures to implement this idea by yourself.
