Hiya, I've been enjoying playing a mostly-vanilla world on 1.14.4 with my girlfriend lately and I've specifically avoided minimap and world map mods like Journeymap because they're too easy to use and break away from the vanilla style too much. So, I've been using vanilla maps to chart the terrain but one thing I'd really like is if the maps had a higher resolution. I'm using 1:8 ratio maps (zoom level 3/4) which I think are the best balance for size and detail, but the detail is still severely lacking. I'd like to be able to have larger maps with more detail, and our computers are more than capable of rendering maps of a higher resolution than the default 128x128.
So, my idea is to simply add higher-res maps. 256x or 512x would be fantastic! They'd work all the same way as the vanilla maps, so I imagine a lot of the code could be borrowed or referenced to make it work, and ideally, they'd be items with a separate ID to the vanilla maps, not replacing them.
